Professional Applications & Engineering Value

This 18-8 Stainless Steel Socket Head Shoulder Screw is engineered to address critical alignment and durability challenges in precision assemblies. The 1" shoulder length with controlled tolerances provides a stable bearing surface for rotating components like gears, pulleys, and linkages, reducing wear and maintaining positional accuracy. The 6-32 UNC coarse thread with Class 3A fit ensures fast, secure fastening in metals and plastics, while the knurled head and hex drive prevent tool slippage during installation. Its high tensile and shear strength, combined with excellent corrosion resistance, makes it ideal for industrial machinery, automation systems, and electronic enclosures where reliability and compliance with RoHS and REACH are paramount.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precise engagement. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005", ensuring consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting use in regulated industries without hazardous substances.
