Professional Applications & Engineering Value

This 316 stainless steel shoulder screw delivers exceptional engineering value in precision machinery and industrial equipment where corrosion resistance and dimensional accuracy are critical. The 10-32 UNF fine thread with Class 2A fit provides superior vibration resistance in automated systems, while the precisely machined shoulder (1/4" diameter with tight tolerances) serves as reliable pivot points in rotating assemblies. The passivated finish enhances corrosion protection in chemical processing and marine environments, and the hex socket drive ensures secure installation in confined spaces. These shoulder screws are engineered to maintain alignment in precision instruments, manufacturing jigs, and robotic components where repeated movement demands exceptional durability and dimensional stability.

Specification Summary & Compliance

This precision shoulder screw features 10-32 UNF threads with Class 2A fit and exact shoulder diameter tolerance of -0.001" to 0". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. The shoulder length maintains 5/8" dimension with 0" to 0.002" tolerance, ensuring consistent performance in precision assembly applications. Thread specifications follow UNF standards with right-hand thread direction and fine thread spacing for optimal fastening performance.
