Threaded-Stud Folding Pull Handles

These handles have a folding grip that drops out of the way when you let go. Insert studs into holes in your surface and secure from the backside to open and close a variety of doors and drawers on chests, crates, furniture, machines, and equipment. All have round grips that allow your hand to pivot in any direction.
Aluminum handles have mild corrosion resistance, are lightweight, and are nonmagnetic.
Stainless steel handles have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

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.

Threaded Plug Gauges

These have a go gauge on one end and a no-go gauge on the other end. They allow you to inspect internal threads on parts. 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.

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.
