Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address critical alignment and corrosion challenges in precision assemblies. The 3/16" shoulder diameter provides an exact pivot or bearing surface, eliminating misalignment in machinery, robotics, and conveyor systems. Its coarse 8-32 UNC thread and Class 3A fit ensure secure fastening under vibration, reducing maintenance needs. The hex socket drive and knurled head allow for efficient installation in confined spaces, while the material's inherent resistance to chemicals and moisture makes it suitable for food processing, marine, and pharmaceutical equipment. This screw delivers reliable performance where high tensile strength and dimensional accuracy are non-negotiable.

Specification Summary & Compliance

This shoulder screw features a Class 3A thread fit per UNC standards, with a shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005" for precision assembly. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety compliance for industrial use.
