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.

Ball-Lever Shafts
Attach a ball knob (not included) to one of these shafts to create custom handles for operating machinery. Mount the other end into a threaded hole. These shafts can also be used to create your own gear levers.
Steel shafts have a black-oxide finish for mild rust resistance.
Stainless steel shafts have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

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.
Stainless steel handle nuts have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.
