Golf Club Shaft Parts, and Knowing Physics for a Better Game

Greater golf equipment knowledge leads to greater confidence and better play, so let’s talk about club shafts.

The shaft is a critical component of the golf club because it transfers the energy of the swing to the clubhead to initiate impact. 

As part of an ongoing series, 2nd Swing Golf Blog is digging into its vaults to help inform today’s golfers a bit more about the clubs and equipment they depend upon. 

Here is an introduction to understanding the golf shaft better, so consumers can feel more confident walking into a store or buying online and then truly making informed purchasing decisions — and — improve their overall game. Here are four things all golfers should know about their clubs, which should help you get more excited about the sport, too, from 2nd Swing Golf Blog:

Golf Shaft Torque

Torque in golf is loaded with misconceptions, so we’ll just stick to the basics here.

The term which expresses the force of twisting, which is measured in degrees. Low torque is a generic term used to describe any shaft with 4 or less degrees of torque. High torque also is a generic term, but used to describe any shaft with more than 4 degrees of torque.

While flex refers to the bending of the shaft, torque is a measurement of how much a shaft twists under a certain load.

A shaft that has more twist is said to have high torque, resulting in less accuracy but more feel. A shaft that twists very little has low torque, increasing accuracy, but decreasing feel.

It’s important to understand torque since it affects both feel and accuracy.

Tip Stiff Steel Shafts

A tip stiff shaft is relatively heavy and low launching compared to other steel shafts. Dynamic Gold was one of the early innovators for its designation to indicate that the shaft is weight-sorted for maximum consistency. Other brands now deep into tip stiff shafts include Matrix, Diamana, Project X, KBS Tour and others.

This diagram demonstrates a variety of shaft variables that go into each one’s design, including weight.

Constant Weight Golf Shafts

It’s the static “weight” so each iron shaft is the same.

Rifle Golf Shafts

The rifling name comes from a series of longitudinal struts that run along the interior of the shaft and provide stability.

Rifle shafts are sorted by frequency, making it possible to produce a tightly controlled set of frequency matched irons. The flex is dictated by a number, such as 5.0 for regular flex.

It is possible to special order shafts in between the designated points such as 5.1 or 6.3. Each digit increase to the right of the decimal represents a single additional cycle, or a 10th of a flex. No one alive can feel the differences between two shafts that are a cycle apart. It generally takes three cycles differential for even the most sensitive players to notice a change.

Tour Flighted Rifle

This version of the rifle is designed to more closely mimic let’s say a Dynamic Gold golf shaft’s ball flight via the manipulation of the flex point throughout the set. Generally, the long irons (1-3) have lower kickpoints to launch the ball, the mid-irons (4-6) have similar kickpoints and the short irons (7-PW) have high kickpoints to control the ballooning.

SensiCore Shaft Inserts 

This is a 4- to 6-gram polymer insert that dampens vibrations. By straddling the fulcrum (balance) point of a shaft, the insert does not impact swingweight. SensiCore (See featured image on top of page.) provides the playability of steel but the softer feel of graphite.
