Professional Applications & Engineering Value

This 316 stainless steel shoulder screw with black oxide finish provides critical solutions for precision machinery and industrial equipment. The UNC coarse threading and Class 3A fit ensure secure fastening in high-vibration environments while preventing cross-threading during assembly. The knurled socket head offers superior torque transmission for tight spaces, and the precisely machined shoulder maintains accurate component alignment in rotating assemblies, pivots, and bearing mounts. With exceptional corrosion resistance from both material selection and surface treatment, this fastener delivers long-term reliability in chemical processing, marine applications, and outdoor equipment where environmental factors would degrade inferior fasteners.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with Class 3A thread fit per UNC standards, featuring a 6-32 thread size with coarse spacing. The shoulder maintains tight diameter tolerance (-0.004" to -0.002") and length tolerance (-0.005" to 0.005") for precision applications. Mechanical properties include Rockwell B79 hardness and verified 70,000 psi tensile strength. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance.
