Professional Applications & Engineering Value

This 316 stainless steel shoulder screw with black oxide finish is engineered to address critical alignment and corrosion challenges in machinery, automation, and precision equipment. The 1/2" shoulder diameter and 1-3/4" shoulder length provide stable rotational control, minimizing wear in bushings and linkages. Its Class 3A UNF fine thread ensures tight tolerances for high-vibration environments, while the hex drive socket head allows efficient torque application in confined spaces. Ideal as an alignment pin or industrial fastener, it reduces maintenance downtime and enhances operational reliability.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with Class 3A thread fit, this shoulder screw maintains tight tolerances: shoulder diameter (-0.004" to -0.002") and shoulder length (-0.005" to 0.005"). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for global industrial use.
