Professional Applications & Engineering Value
This ultra-precision lead screw is engineered to solve critical challenges in high-accuracy linear motion systems. Machined from 303 Stainless Steel, it provides superior corrosion resistance and strength, essential for CNC machinery, precision assembly equipment, and medical devices where contamination and failure are not an option. The rounded Acme thread profile and 4 thread starts work in concert to deliver a 0.5" travel per turn with remarkably low backlash, enabling faster positioning and improved efficiency without sacrificing the legendary ±0.0006" accuracy. This combination of speed and precision directly addresses the engineering need for both high throughput and micron-level repeatability in automation, metrology, and other demanding industrial applications.
Specification Summary & Compliance
This 1/2"-8 lead screw features a right-hand, fully threaded Rounded Acme thread form. It delivers a precise travel distance of 0.5" per turn with an accuracy of ±0.0006" per inch. The component is manufactured from 303 Stainless Steel with a tensile strength of 90,000 psi and a hardness of Brinell 160. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards.
