Fitting
Golf shafts can be fitted to each club per the golfer's liking. There is no set rule that a certain flex point must be applied to the club.
Flex
The flex simply refers to how much the shaft bends. The letters X (extra stiff), S (stiff), R (regular), and A (amateur) are denoted on the shaft.
Materials
Graphite and steel make up a golf shaft. The steel shafts are a little more expensive to fit, and they are also stiffer than graphite shafts.
Torque
The torque is the factor on the shaft that determines its resistance on the downswing. Torque is often measured in degrees. The lesser degrees involved, the more stable the shot will be.
Wear on the Shaft
If the shaft is properly fitted on the club to the head, the shaft will never wear down or lose its torque or flexing point.
