Professional Applications & Engineering Value

This 316 stainless steel shoulder screw addresses critical engineering challenges in precision machinery and industrial equipment where corrosion resistance and dimensional stability are paramount. The 8-32 UNC coarse thread with Class 3A fit ensures vibration-resistant fastening in high-stress applications while the precisely machined shoulder provides reliable bearing surfaces for rotating components. Ideal for precision positioning in manufacturing equipment, conveyor systems, and automated machinery, the screw's 70,000 psi tensile strength withstands dynamic loads while maintaining alignment accuracy. The knurled socket head combined with hex drive design prevents tool slippage during torque-critical installations, making it particularly valuable in maintenance-intensive environments where repeated disassembly is required.

Specification Summary & Compliance

Manufactured to exacting standards with Class 3A thread fit and UNC coarse thread profile (8-32 size), this shoulder screw maintains tight dimensional tolerances including shoulder diameter (-0.004" to -0.002") and shoulder length (-0.005" to 0.005"). The component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental regulation adherence for global manufacturing applications. With material hardness of Rockwell B79 and mechanical properties verified to specified tensile and shear strength values, this precision fastener delivers reliable performance in critical industrial applications.
