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-Hole Pull Handles
Rectangular grips have a flat surface that keeps your hand from slipping, but may be less comfortable than round and oval grips.
Stainless steel handles have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

Cam Handles
Use these standard cam handles for most clamping applications. Push down on the handle and the head applies pressure to quickly draw two parts together for fast adjustments. Clamping distance is how far the handle will draw parts together when clamped.
Threaded-hole handles install on a threaded stud.
Threaded-stud handles mount into a threaded hole.
Aluminum handles have mild corrosion resistance, are lightweight, and are nonmagnetic.

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. Aluminum handles are lightweight and have good corrosion resistance.

Threaded Plug Gauges with Calibration Certificate
These gauges come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy. They allow you to inspect internal threads on parts. All have a go gauge on one end and a no-go gauge on the other end. A taperlock handle lets you quickly replace worn gauges.
Check the minimum internal thread size with the go gauge end, and check the maximum internal thread size with the no-go gauge end. A part is within tolerance if it’s easy to thread the go gauge into the part but difficult to thread the no-go gauge more than two turns.
Threads have different classes of fit. Thread fit designates the tightness or looseness of mating threads. For example, inch threads with a 3B fit have tighter tolerances than threads with a 2B fit.
