Professional Applications & Engineering Value
Engineered for precision industrial assemblies, this 8-32 UNC shoulder screw addresses critical alignment and vibration challenges in machinery manufacturing. The 18-8 Stainless Steel construction provides essential corrosion resistance for equipment exposed to moisture, chemicals, or outdoor elements. The integrated Nylon Patch thread locker delivers reliable vibration resistance without requiring secondary locking components, streamlining assembly processes in automotive, aerospace, and industrial automation applications. The precisely controlled shoulder diameter (3/16") and length (1/2") with tight tolerances ensures accurate component positioning in rotating assemblies, pivot points, and guide mechanisms, while the coarse UNC threading enables rapid installation in high-volume production environments.
Specification Summary & Compliance
This shoulder screw maintains Class 2A thread fit per UNC standards with precise shoulder diameter tolerance (-0.001" to 0") and shoulder length tolerance (0" to 0.002"). Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material compliance for global industrial applications. The combination of 70,000 psi tensile strength and controlled dimensional accuracy meets rigorous industrial fastener requirements.
