Professional Applications & Engineering Value
This 6-32 UNC shoulder screw is engineered to solve critical alignment and durability challenges in industrial assemblies. The 18-8 stainless steel material, enhanced by a passivated finish, provides excellent resistance to corrosion and wear, making it ideal for machinery, automotive, and electronic enclosures exposed to demanding conditions. The precise shoulder fit with minimal tolerances ensures components like gears, linkages, and bearings are accurately positioned, reducing misalignment and premature failure. Its hex socket head allows for compact installation in tight spaces, while the coarse UNC thread and 70,000 psi tensile strength offer robust fastening that withstands dynamic loads and vibrations, delivering long-term reliability in heavy-duty applications.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent assembly. Key dimensions include a thread diameter of 0.138", shoulder diameter of 5/32" (tolerance: -0.001" to 0"), and shoulder length of 1/8" (tolerance: 0" to 0.002") for precise engineering. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances and suitable for global industrial use.
