Professional Applications & Engineering Value

This 8-32 UNC shoulder screw delivers critical engineering value in applications requiring precise component positioning and rotational stability. The 18-8 stainless steel construction with passivated finish provides excellent corrosion resistance for machinery operating in humid or chemically aggressive environments. The precisely controlled shoulder diameter and length (7/32" diameter, 3/8" length) ensures accurate alignment of bearings, gears, and linkages while preventing axial movement. The hex socket drive allows for high-torque installation in confined spaces, making these shoulder screws ideal for precision instruments, automation equipment, and mechanical assemblies where component misalignment would compromise performance. The combination of 70,000 psi tensile strength and controlled tolerances addresses common industrial challenges of vibration-induced loosening and premature wear in rotating assemblies.

Specification Summary & Compliance

This precision shoulder screw features 8-32 UNC Class 2A threads with 3/16" thread length and controlled shoulder dimensions (7/32" diameter with -0.001" to 0" tolerance, 3/8" length with 0" to 0.002" tolerance). Manufactured from 18-8 stainless steel with passivated finish, the fastener meets mechanical properties of 70,000 psi tensile strength and Rockwell B55 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
