Chrome-Plated Hardened Multipurpose 4140 Alloy Steel Rods
- Yield Strength: 100,000 psi
- Hardness: Rockwell C30 (Hard)
The chrome plating on these rods increases corrosion resistance. They are hardened for increased abrasion and impact resistance. Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress.

Metric 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, size, and pitch. Class 7e and 7H components are compatible.
932 bearing bronze components are more wear resistant than brass components. They have good machinability and fair corrosion resistance.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

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