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.

Lead Screws—Right-Hand Thread

Carbon Steel—Carbon steel components are easier to machine than alloy steel components.

Zinc-Plated Carbon Steel—Zinc-plated carbon steel components have mild corrosion resistance and are easier to machine than alloy steel components.

Alloy Steel—Alloy steel components are harder and stronger than carbon steel components.

18-8 Stainless Steel—18-8 stainless steel components have good corrosion resistance.

316 Stainless Steel—316 stainless steel components have excellent corrosion resistance.

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.

Hex-Head Screws—Right-Hand Thread

Hex head screws fasten heavy loads. They’re generally shorter than lead screws and can be tightened with a wrench. Length is measured from under the head.

Carbon Steel—Carbon steel components are easier to machine than alloy steel components.

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.

Flange Nuts—Right-Hand Thread

Flange nuts move objects along the length of a lead screw. Flange nuts have a wide machinable flange for custom mounting.

932 Bearing Bronze—932 bearing bronze components are more wear resistant than brass components. They have good machinability and fair corrosion resistance.

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.
