Handle Nuts


Style A

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.

Zinc-Plated Iron—Zinc-plated iron handle nuts have corrosion resistance.

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, thread size, and number of thread starts.

Thumb Nuts—Right-Hand Thread

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

Cast Iron—Cast iron components have good machinability and high strength.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.

Wing Nuts


Style 5	Style 8

The easiest nuts to twist on and off by hand, these are commonly used to fasten parts that need to be frequently disassembled, such as access panels and covers. The wings give you more leverage than knurled-head nuts, so you can apply greater torque and achieve a tighter fit.

Style 8

Zinc-Plated Iron—A step up from plain iron, the zinc plating withstands occasional exposure to moisture.

Iron—Best for dry environments since moisture will cause these nuts to rust.
