About this category

S45C parallel keys already cut to length — width, height and length are all finished dimensions, ready to fit straight into the keyway with no further machining. The sibling category carries 300/350 mm standard bar for those who prefer to cut their own or stock several lengths. S45C is the general-purpose carbon steel for power transmission, balancing strength and machinability.

How to choose

• Sizes read width x height x length; width and height must suit both the shaft and the hub keyway.
• Length can be shortened, width and height cannot — get those right first.
• Use 304 stainless keys where moisture or chemicals are involved.
