Ultra-Machinable 360 Brass Rods
With the highest lead content, 360 is the easiest brass alloy to machine. Known as free-machining and free-cutting brass, it handles high-speed drilling, milling, and tapping with minimal wear on your tools. You’ll often see it made into gears, pinions, and lock components.

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.
Round Nuts—Right-Hand Thread
 |
Round nuts move objects along the length of a lead screw.
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.
