What does "torque" mean for a shaft?
“Torque” is a property of golf shafts that describes how much the shaft is prone to twisting during the golf swing. All shafts, steel and graphite, exhibit torque, which is measured in degrees. A high-torque shaft will twist more than a low-torque shaft. Put another way, some shafts resist twisting better than others.
What does high torque mean in a golf shaft?
The torque is how much a golf club will resist bending during the swing. A golf shaft with a higher toque means that the shaft is going to twist more, and a golf shaft with a low torque will twist much less. Generally speaking, golfers with faster swing speeds are going to want lower torque golf shafts.
How much does shaft torque affect performance?
Shaft torque affects performance a little bit, but not nearly as much as does the shaft’s weight, overall stiffness design and bend profile design. And here’s why. Torque and RPM are measured quantities of engine output; Power is calculated by the equation (HP = Torque x RPM/5252) Understanding the relationship between the two factors also requires knowing a little about an engine’s parts.
What does higher torque on a golf shaft mean?
A shaft with a lower torque rating means the shaft better resists twisting; a shaft with a higher torque rating means the shaft is more prone to twisting (all other things being equal). A golfer's swing, and the clubhead attached to the end of the shaft, exert forces on the shaft that lead to twisting.
What is a shaft torque?
Shaft torque is measured by a device that records the amount a shaft will twist under a certain amount of force, and it's recorded in degrees. A shaft with 3 degrees of torque will twist less than a shaft with 5 degrees of torque, and so on.
What torque shaft should I use?
1) Players who tend to hook the ball will benefit from a lower torque shaft. Players who tend to slice the ball will benefit from a higher torque shaft. 2) Players who swing faster need lower torque.
What is torque and kick point in golf shaft?
Kick point will influence how the club feels and what trajectory the ball launches at. Torque: This measures, usually in degrees, the shaft's resistance to twisting. Low torque (around 2-3 degrees) means it doesn't twist, or torque, much at all, whereas high torque (around 5+ degrees) means the shaft twists a lot.
What does high torque mean?
In simple terms, the more torque an engine has, the better suited it is to hard work such as towing, hauling or climbing steep grades. This is why torque is often the figure of utmost importance when moving something big and heavy, like a truck with a trailer attached.
How does torque affect ball flight?
If we think about torque affecting how the club head is delivered to the ball at impact, you can imagine that it would affect ball flight. One study in 2017, showed that shafts with a higher torque caused a more open club face at impact which led to a slightly higher launch that tended to go right.
What weight golf shaft should I use?
In general, golfers with slower swing speed and tempo can and should play a lighter shaft. Golfers with very fast speeds and tempo should play heavier shafts. Driver shafts typically weigh 55-60 grams for men and 45-50 grams for ladies.
How does shaft affect ball flight?
Generally, the more flexible a shaft, the higher the ball flight. The lower the bend point in the shaft, the higher the ball flight (minor affect). Generally, the stiffer the shaft, the lower the ball flight. The higher the bend point, the lower the ball flight (minor affect).
How do you measure torque on a shaft?
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
How do I know if I need a stiff shaft?
To check your swing speed a shot tracking device will be the most accurate method. Based on your swing speeds here are our recommendations: 80-95 mph swing speeds should use regular shafts. 90-105 mph swing speeds should use stiff shafts.
Is stiff shaft better than regular?
What's the difference between regular and stiff shafts? A stiff shaft is firmer and harder to bend than a regular shaft, and so more often than not, they're also heavier in weight. As a rough rule of thumb, the more speed you generate, the stiffer your shafts should be.
Will senior flex increase distance?
If you are playing with a regular shaft currently and it is not the right fit for you, the senior flex shaft could help you increase distance.
How is shaft torque calculated?
For motors, find torque (in ft-lb) using this equation: T = (HP*5252)/rpm.
How is engine shaft torque calculated?
Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.
What is half shaft torque?
Description. ATi's Half Shaft Telemetry Systems transmit torque signals from rotating shafts to a stationary telemetry receiver. It connects directly to strain gages adhered to the shaft, converting it into a torque sensor, allowing it to transmit shaft torque while the vehicle is operating.
How do you determine torque?
Measure the distance, r , between the pivot point and the point the force is applied. Determine the angle θ between the direction of the applied force and the vector between the point the force is applied to the pivot point. Multiply r by F and sin θ and you will get the torque.

How Does Torque in Steel Shafts Compare to That in Graphite Shafts?
In steel shafts, because the type of steel material is the same throughout the entire shaft, the torque exists in a very narrow range of degrees, one that is much more narrow than in graphite shafts.
What torque is needed for a graphite shaft?
So for most golfers, as long the torque of a graphite shaft is between 3.5 and 5.5 degrees - which is the case for the vast majority of graphite shafts today - the golfer will be OK and torque will never be a factor to worry about in the shaft fitting.
How much torque does graphite have?
This allows the torque in graphite shafts to range from as high as 7 or 8 degrees to as low as 1 degree, while in steel this range is only from a little more than 2 degrees to a little under 4 degrees.
What happens if you use too high a torque rating?
a strong golfer who uses shafts with too high a torque rating might produce shots that leak to the fade side;
What is twisting in golf?
A golfer's swing, and the clubhead attached to the end of the shaft, exert forces on the shaft that lead to twisting. This twisting is simply a part of the swing.
What is torque in golf?
Torque is defined as "a force that produces or tends to produce rotation or torsion." If you think of a golf shaft as an axis, the heel of the head is centered on that axis, but the toe – as well as most of the clubhead's weight – is off-center. When you swing the club, the head twists around the shaft. The toe gets "left behind" as you start your downswing, then it "catches up" and returns to its normal position at impact. The shaft resists that twisting motion, allowing only a certain amount. The twisting that is allowed, measured in degrees, is the shaft's torque.
Why do golfers use low torque shafts?
Power players such as PGA Tour golfer Dustin Johnson generally use low-torque shafts to better help them control the ball. Golf shafts have many technical specifications that you, as an average golfer, likely never consider. You are indirectly aware of them because they affect how your clubs feel when you swing them.
Why are you aware of the specs on your golf clubs?
You are indirectly aware of them because they affect how your clubs feel when you swing them. But those specs affect how your club performs, and club fitters take them into account when they fit you for new clubs. Torque is one of those "invisible" specs, and it has a bigger effect on club performance than you might expect.
How much twist does a high torque shaft have?
A low-torque shaft may allow only 2 degrees (or less) of twist, while a high-torque shaft might go all the way to 6 degrees. That might not sound like a lot, but it certainly can affect your accuracy.
What happens when you swing a golf club?
When you swing the club, the head twists around the shaft. The toe gets "left behind" as you start your downswing, then it "catches up" and returns to its normal position at impact. The shaft resists that twisting motion, allowing only a certain amount.
Does torque matter in golf shafts?
The material used to make your shaft matters. While torque always has been a factor in shaft performance, the inherent stability of steel shafts made torque relatively unimportant to everyday golfers.
Can graphite shafts be duplicated?
With the introduction of graphite shafts, however, manufacturers now can tailor shafts to behave anyway they want; they can duplicate the performance of any material from classic hickory to high-tech steel. But this comes at a price; the less torque you want, the more you have to pay for it.
Why is shaft torque important?
Shaft torque becomes increasingly important the faster you swing. Torque is the measure of how much the shaft twists during the golf swing. It may be hard to imagine this even happening, but shafts are made with that particular fact in mind. They are even made to resist it more or less, depending on your swing and what kind ...
What happens when you have less torque in your golf club shaft?
When you have more torque in your club shaft it is said that your shots can be less accurate but go further and have a nice soft feel.
Why does my golf club go faster?
This also means you can hit the ball a little further, because at the time the club strikes the ball the torque can cause the club head to go faster.
Why does a steel shaft have less torque?
A steel shaft will have less torque simply because of the material it is made of. A degree of 3 to 4 is normal for a steel shaft. Graphite shafts can have a lot more torque. Since graphite is not a solid piece of material, the torque can be much higher; to degrees of 7 or 8.
When you strike the ball, do you want your club head to be square?
When you strike the ball, you want your club head to be as square to your target as possible. When the club head twists, it can make the club head a degree or two open or closed when it makes contact. Therefore you want less torque when you are looking to straighten your ball flight.
Does Tiger Woods know how much torque he needs?
Certainly Tiger Woods knows exactly how much torque he needs for every club in his bag , but for a beginner it won't matter much. Torque should be one of the last things you look at when trying to improve your game. Golfweeks' Adam Woodard breaks down the results from the match.
What is torque in a car?
Torque is really pretty simple: it’s the shaft’s resistance to twisting. Torque is measured in degrees (meaning: how many degrees will the shaft twist under a certain amount of force), and you’ll typically see measurements as low as 2° and as high as 5°, 6°, or 7°.
Which player will benefit from a lower torque shaft?
1) Players who tend to hook the ball will benefit from a lower torque shaft. Players who tend to slice the ball will benefit from a higher torque shaft.
Why should you care about torque?
You should care because torque is a major component in how a shaft feels, much more than flex . You could have an XX-stiff shaft with high torque, and it might feel “smooth” or even “whippy.”. Alternately, you could have a senior flex shaft with low torque that can feel “boardy.”.
How many shots does each golfer hit with each shaft?
Each golfer hit 10 shots with each shaft and the results were measured by our FlightScope X2 launch monitor. All testing was done at the range at The Bridges of Poplar Creek Country Club.
Does Tester 3 like low torque shafts?
Tester 3 hates boardy feeling shafts, so, despite the fact that his most-hated miss is a hook, he does not like low torque shafts. On the other hand, Tester 1 doesn’t like loose feeling shafts despite the fact that he needs all the help he can get to square the club face. Historically, he has found better success with lower torque shafts because he feels like he can release the club more aggressively.
Does torque affect where the ball ends up?
Torque also has a major impact on where the ball ends up. All other things being equal, a shaft with higher torque will lead to a club face that is pointed further left (for a RH golfer) at impact…but we know “all other things” are rarely equal when you add in the human element.
Is torque a rule?
Torque matters, and, like flex and weight , there are no easy rules to follow. You need to try a variety of things and be fit into the shaft that will work best for you.
What is torque in golf?
Torque is the simply the amount a golf shaft (shown in blue) twists when subjected to a known amount of force (usually one foot-pound of force is applied) and the torque value is always expressed in degrees. It is a term commonly associated with composite or graphite shafts, but steel shafts have a certain degree of torque too.
How much torque does a 46" shaft have?
For the sake of example, this 46” raw shaft (with a 43” beam length) happens to measure a torque of 6.0º using 1 foot-pound of force. By most standards, this torque rating may seem high.
Why are shafts less accurate?
One of the reasons shafts with higher torque values are considered less accurate can be attributed to the cost. Often times the higher torque wood shafts (above 6°) will be less than $9 retail and may not be 100% graphite, but have a certain percentage of fiberglass mixed in. One clue is to look at the shaft weight.
What is a low cost graphite shaft?
Low cost graphite shaft are construct ed with low modulus (lower strength) materials. Often times these shafts will exhibit both high torque and a softer tip section. In the hands of a stronger player, this combination would be less accurate than a lower torque model.
What happens if you use less material on a shaft?
If less material is used (due to the lighter weight), there is less material available to control torque or resist twisting.
Does steel have torque?
It is a term commonly associated with composite or graphite shafts, but steel shafts have a certain degree of torque too. However the amount cannot be independently changed from the frequency (or stiffness) of the shaft like a composite design, thus torque of steel shafts is generally not listed by the manufacturer.
Is there a standard for golf shafts?
I like to say “the only standard in the golf industry is there are no standards.”. Each manufacturer has an internal method for measuring torque that will vary from one to the next. However, each shaft by the manufacturer will be measured using the exact same clamping dimensions and force for all their shafts.
What is torque in golf shafts?
Torque is a function of the shaft’s GJ profile, where G is the shear modulus (resistance of the material to twisting) and J is the shape (diameter and wall thickness). In a carbon shaft, we can vary the G by changing the type of carbon we use of the size of the torsional ply we use. Because of the steels used in golf shafts, G is always the same, regardless of the heat treatment or alloy. And since most shafts have a very similar diameter profile and a small wall thickness variation, GJ, and hence torque, changes very little across steel golf shafts.
Why is torque mentioned more often in relation to composite golf shafts vs. steel?
steel is because composite shafts offer so many choices in torque while in steel, such a vast selection simply does not exist.
Is Zero Torque Possible?
The answers to this question ranged from, “Possible, but difficult” to “Impossible.” What everyone agreed on, however, is that it’s not desirable . MRC pointed out that a shaft with zero torque would transfer very little energy to the golf ball . Others mentioned the drawbacks of extremely rigid feel and the lack of forgiveness
What does a lower torque shaft feel like?
Lower torque shafts feel stiffer . What many players describe as a shaft feeling too soft or too stiff may not be related to flex as much as it’s related to torque. Additionally, the shaft’s torque will affect how it feels on mishits. Shafts with lower torque will feel harsher and more punishing on mishits. Conversely, shafts with higher torque ...
What is torque in mechanics?
Torque is the measurement of a shaft’s resistance to rotational twisting . Torque is expressed in degrees – the higher the number, the less resistance.
Why is torque important?
Torque, just like shaft flex, is an important factor in selecting a shaft. Not only does it have a huge impact on the way a shaft will perform , it’s one of the biggest factors in how a shaft feels.
What is clamped on a shaft?
The butt of the shaft is clamped, a force is applied to the tip, and the degrees of twisting are measured. What can vary are the size of the clamp, the distance between the clamp and the force, and the amount of force used.
What is torque in golf?
There’s yet another factor that influences a shaft’s performance: torque. Torque is simply defined as “resistance to twisting,” and it’s measured in degrees. Basically, a low torque value means the shaft will twist very little during the swing; a high-torque shaft twists more.
Why do golfers need torque?
Golfers with slower swing speeds (less than 90 mph) typically need higher torque to help them return the clubface to square at impact. Of course, a shaft’s torque must mesh with other qualities (length, weight, flex etc.) to produce the desired results for any individual golfer.
What is torque range for graphite shafts?
Still, the torque range that applies to most golfers is relatively small, between 3.5° – 5.5°. Like most clubfitting elements, there are no absolutes when it comes ...
How fast does a golf club need to be to match torque?
The basic rules when choosing a shaft with the right torque are as follows: Golfers with high swing speeds (100+ mph) typically need lower torque shafts.
What is the shaft of a golf club?
By now, most golfers are aware that the shaft is the so-called “engine of the golf club .” They have a basic understanding of how length, weight and flex affect ball flight and shot distance. They may even be familiar with the concept of the shaft’s bend or kick point.
