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.

Quick-Release Shaft Collar Handles
These threaded handles take the place of a set screw, allowing you to move set screw shaft collars without additional tools—useful for when the collar serves as a stroke limiter or mounting clamp. The handle keeps your collar secure on the shaft, then lets you loosen and tighten the collar for quick adjustments.
Black-oxide steel handles have some corrosion resistance. 303 stainless steel handles have excellent corrosion resistance. Aluminum handles are lightweight and have good corrosion resistance.
