Professional Applications & Engineering Value
This 8-32 UNC shoulder screw delivers critical engineering value in precision assemblies where component alignment and rotational stability are paramount. The 18-8 stainless steel construction with passivated finish provides excellent corrosion resistance for demanding environments including manufacturing equipment, automation systems, and precision instruments. The precise shoulder diameter (7/32") and shoulder length (5/16") with tight tolerances ensure accurate bearing surfaces and proper component spacing, eliminating misalignment issues. The hex socket head allows for high-torque installation in confined spaces, while the Class 2A thread fit on the UNC coarse threads ensures reliable engagement even in vibration-prone applications. This combination of precision machining and material properties solves common industrial challenges including component slippage, corrosion-induced failure, and assembly inaccessibility.
Specification Summary & Compliance
This precision shoulder screw features Class 2A thread fit with UNC coarse threads (8-32 size) and maintains tight shoulder diameter tolerance (-0.001" to 0") and shoulder length tolerance (0" to 0.002"). Manufactured to exacting standards using 18-8 stainless steel with passivated finish, the fastener is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international regulatory requirements for industrial components.
