Professional Applications & Engineering Value

This 8-32 UNC thread shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. The 316 Stainless Steel material provides excellent resistance to chemicals and moisture, making it suitable for applications in chemical processing, marine equipment, and food machinery. The knurled socket head with a hex drive ensures a firm grip, reducing tool slippage during high-torque installations. Combined with a Class 3A thread fit and coarse thread spacing, it offers quick assembly and disassembly while maintaining tight tolerances. The precision-machined shoulder acts as a reliable spacer or pivot in rotating assemblies, reducing wear on connected components and extending service life in demanding environments like automation systems and precision instruments.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Key dimensional tolerances include a shoulder diameter of 7/32" (tolerance: -0.004" to -0.002") and shoulder length of 1/8" (tolerance: -0.005" to 0.005"). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial applications.
