- Durable, long-lasting performance with Rockwell B79 hardness ensuring resistance to deformation under load.
Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw is engineered for precision assemblies where exact alignment and corrosion resistance are critical. The 1/2" shoulder diameter with controlled tolerances acts as a pivot or bearing surface, eliminating the need for additional bushings in machinery, conveyor systems, and robotic arms. Its Class 3A thread fit and UNC coarse threads provide reliable engagement in metal and plastic components, reducing the risk of cross-threading. The knurled socket head with a 1/4" hex drive ensures secure tool grip, even in oily conditions, speeding up maintenance. Ideal for industrial automation, food processing equipment, and marine applications, this screw’s high tensile and shear strength supports heavy dynamic loads while complying with RoHS and REACH for safe use in regulated industries.
Specification Summary & Compliance
This shoulder screw adheres to ASME B18.3 specifications, 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 dimensional accuracy. It is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial components.
