Helix 16902 Right Hand Thread 1 Start Trapezoidal Lead Screw, 16mm Rod Diameter, 4mm Lead, 3600mm Length

This Nook acme screw is a lead screw, or power screw, with a trapezoidal thread form for translating turning motion into linear motion. It is made of American Iron and Steel Institute (ANSI) 4140 steel for high fatigue strength and resistance to abrasion. It has a rolled thread for a stronger, smoother surface than cut thread, and the centralizing thread form resists wedging and binding. This acme screw has a right-hand, 1 start thread and is suitable for use in linear actuators, machine slides, vises, presses, and jacks, among others.

Nook Industries manufactures mechanical and electro-mechanical actuators, assemblies, and components. The company, founded in 1969 and headquartered in Cleveland, OH, meets International Organization for Standardization (ISO) standard 9001.
