Professional Applications & Engineering Value
This 316 stainless steel shoulder screw with UNC coarse thread and Class 3A fit addresses critical alignment and corrosion challenges in precision assemblies. The knurled socket head provides superior torque transmission while the precisely machined shoulder serves as a reliable bearing surface or pivot point in machinery, automation equipment, and precision instruments. The right-hand thread direction ensures standard installation compatibility across industrial applications. Engineered to maintain dimensional stability under load, this fastener solves common issues of component misalignment and thread wear in high-vibration environments, making it ideal for industrial shoulder screw applications requiring both mechanical strength and corrosion resistance.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit for superior tolerance control. Features include 8-32 UNC thread size, 5/16" head diameter, 3/16" shoulder length with tight tolerances (-0.005" to 0.005"), and shoulder diameter tolerance of -0.004" to -0.002". Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
