About Shaft Collars
Shaft collars are useful for holding and positioning components on a shaft. They can also serve as mechanical stops and stroke limiters.

Threaded Shaft Collars
To install, thread these one-piece collars onto the end of your shaft. They clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screw to secure.
Black-oxide steel collars have some corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.
