Professional Applications & Engineering Value
Engineered for demanding industrial applications, this nickel alloy shoulder screw delivers exceptional performance where corrosion resistance and mechanical reliability are paramount. The 8-32 UNC coarse thread with Class 3A fit provides superior engagement in metal components, resisting vibration loosening in machinery, automation systems, and precision equipment. The 3/16" shoulder length with tight tolerances serves as precise spacing elements in rotating assemblies, while the knurled socket head with hex drive ensures secure tool engagement during high-torque installation. Ideal for chemical processing equipment, marine applications, and aerospace components where Rockwell B60 hardness and environmental compliance are critical requirements.
Specification Summary & Compliance
This precision shoulder screw features 8-32 UNC coarse threads with Class 3A fit for superior thread engagement. Shoulder dimensions maintain tight tolerances with diameter at 3/16" (-0.004" to -0.002") and length at 5/16" (-0.005" to 0.005"). Manufactured to exacting standards with Rockwell B60 hardness and mechanical properties including 70,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) with exemption 6(c) and REACH (EC 1907/2006) regulations for hazardous substances.
