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.

Machine Handles
These handles are often used for operating machinery.
Threaded through-hole handles allow long shafts to thread through these handles for mounting versatility.
Unthreaded through-hole handles allow tapping custom threads or securing them with a set screw. Long shafts can pass through these handles for mounting versatility.
Machinable-hub handles permit milling specific holes or keyways in the hub to meet your specifications. They can also be welded in place.
Iron handles are zinc plated for corrosion resistance.

Metric Steel and Iron Wing Nuts


These nuts have wings that provide more leverage for greater torque while tightening than knurled-head thumb nuts.
Zinc-plated wing nuts are corrosion resistant in wet environments.

Acme Lead Screws and Nuts

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. To ensure compatibility, please select components that have the same thread direction and size.
Cast iron components have good machinability and high strength.
Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.
For technical drawings and 3-D models, click on a part number.

Thumb nuts fasten and position lead screw components. Thumb nuts are easy to grip and tighten by hand for quick assembly and disassembly.

Handles fasten and position lead screw components. Handles are easy to grip and tighten by hand for quick assembly and disassembly.
