• Easy installation and maintenance with hex socket drive design requiring only 1/8" hex key

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw delivers exceptional engineering value in precision machinery and industrial equipment where alignment accuracy and corrosion resistance are critical. The 3/8" shoulder length provides precise spacing and rotational support for moving components in assemblies, while the Class 3A thread fit ensures secure fastening without backlash. The UNC coarse thread pattern facilitates quick assembly and disassembly in maintenance operations, and the knurled head texture enhances grip during installation in confined spaces. With Rockwell B79 hardness, this fastener maintains dimensional stability under load, making it ideal for pivots, axles, and guide pins in manufacturing equipment, automotive systems, and marine applications where saltwater corrosion resistance is essential.

Specification Summary & Compliance

This precision shoulder screw features 10-24 UNC coarse threads with Class 3A thread fit for superior engagement, manufactured to ASME B18.3 specifications for dimensional consistency. Critical tolerances include shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005" ensuring precise component alignment. The fastener is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
