Handle Nuts
Use these handles for quick assembly and disassembly. Their offset grip provides leverage, making them a good alternative to wing nuts. Long shafts can thread through these handles for mounting versatility.
Iron handle nuts with a zinc-plated finish have corrosion resistance.

Threaded-Hole Ball Knobs
Install these traditional, easy-to-grip ball knobs on a threaded stud. They're good for control levers and push-pull rods.
Stainless steel knobs have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.
Aluminum knobs have mild corrosion resistance, are lightweight, and are nonmagnetic.
Brass knobs have good corrosion resistance and are nonmagnetic.
Plastic knobs are a lightweight alternative to metal. They resist oil, grease, and solvents. Phenolic has good scratch 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.
