Low-Profile Adjustable Handles
Choose these handles when vertical space is limited. Also known as clamping handles, use them for applications involving frequent positioning, tightening, and holding adjustments. Lift the handle to rotate freely. Release it to engage and tighten.
Nylon plastic handles are a lightweight alternative to metal. They resist oil, grease, and solvents.
Zinc handles have good corrosion resistance.
Threaded-stud handles mount into a threaded hole.

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.
