Professional Applications & Engineering Value

This precision-engineered shoulder screw delivers exceptional performance in demanding industrial applications where corrosion resistance and mechanical reliability are critical. The 18-8 stainless steel construction provides superior protection against rust and chemical exposure, while the Class 3A thread fit ensures precise engagement in left-hand thread applications commonly found in rotating machinery, conveyor systems, and specialized equipment. The knurled socket head with 3/32" hex drive offers excellent torque transmission, preventing tool slippage during installation. The precisely controlled shoulder dimensions (5/32" diameter, 3/8" length) enable accurate component alignment and spacing, making these UNC coarse thread fasteners ideal for precision assemblies, pivot points, and bearing mounts where dimensional stability is paramount.

Specification Summary & Compliance

This shoulder screw features Class 3A thread fit with 6-32 UNC coarse threads in left-hand orientation, ensuring precision threading for industrial applications. The shoulder maintains tight tolerances with diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005". Manufactured from 18-8 stainless steel with Rockwell B55 hardness, the fastener delivers 70,000 psi tensile strength and 35,000 psi minimum shear strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting international environmental and safety standards for industrial components.
