Professional Applications & Engineering Value
This 8-32 UNC shoulder screw delivers critical engineering solutions where precise component alignment and rotational stability are paramount. Manufactured from high-strength alloy steel, it addresses common industrial challenges such as shaft misalignment, bearing surface wear, and assembly vibration. The black oxide finish enhances corrosion resistance in harsh operating conditions while maintaining dimensional stability. The coarse thread design ensures rapid assembly and disassembly in maintenance-intensive applications across machinery, automotive, and precision equipment sectors. The precisely machined 3/16" shoulder diameter and 7/16" shoulder length create reliable pivot points and alignment surfaces in rotating assemblies, reducing wear on adjacent components and extending service life.
Specification Summary & Compliance
This precision shoulder screw maintains Class 2A thread fit per UNC standards with exact 3/16" shoulder diameter (-0.001" to 0" tolerance) and 7/16" shoulder length (0" to 0.002" tolerance). Manufactured to industrial specifications with 140,000 psi tensile strength and Rockwell C32 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across global markets.
