Professional Applications & Engineering Value

This 18-8 Stainless Steel shoulder screw is engineered to address common industrial challenges, such as component misalignment and corrosion-induced failure. The 5/16" shoulder length provides a precise pivot or spacer in machinery, while the 8-32 UNC coarse thread ensures rapid, secure fastening in high-vibration applications like automotive assemblies and conveyor systems. Made from corrosion-resistant stainless steel, it withstands exposure to moisture and chemicals, extending service life in demanding environments. The socket head with knurled texture enhances tool engagement, preventing slippage during installation and supporting efficient maintenance cycles in production lines.

Specification Summary & Compliance

This shoulder screw features a Class 3A thread fit for tight tolerances, with a shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005". It adheres to UNC thread standards and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory alignment for industrial use.
