Professional Applications & Engineering Value

This ultra-precision lead screw delivers critical performance where minute positioning errors are unacceptable. Manufactured from 303 Stainless Steel, it resists corrosion in medical, laboratory, and food processing equipment while maintaining dimensional stability. The rounded Acme thread profile minimizes friction and distributes loads evenly, extending service life in high-cycle applications. With ±0.0006" accuracy per inch of travel, engineers can achieve sub-thousandth precision in CNC positioning stages, optical alignment systems, and metrology instruments. The fully threaded 6-inch length and right-hand thread direction make it ideal for compact linear actuators requiring precise displacement control in automation and semiconductor manufacturing.

Specification Summary & Compliance

This precision component features a 1/8"-20.8 rounded Acme thread with Class 2A tolerance equivalents, single thread start configuration, and 0.048" travel distance per revolution. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The 90,000 psi tensile strength and Brinell 160 hardness confirm mechanical reliability for continuous operation in precision motion control systems.
