Professional Applications & Engineering Value

This 10-32 UNF shoulder screw is engineered to solve critical industrial fastening challenges where vibration loosening and component misalignment are common failures. The nylon patch locking technology creates a permanent chemical bond that resists back-out under continuous stress, eliminating the need for secondary locking devices. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance for machinery, automotive, and electronic assemblies exposed to moisture or chemicals. The precision-machined 1/4" shoulder with tight tolerances ensures accurate component positioning in rotating assemblies, pivoting mechanisms, and bearing mounts. The fine thread configuration offers superior holding power in softer materials and thin sections, while the socket head design with 1/8" hex drive allows for high-torque installation in confined spaces.

Specification Summary & Compliance

This shoulder screw features Class 2A thread fit per UNF standards with precise 1/4" shoulder diameter (-0.001" to 0" tolerance) and 3/16" shoulder length (0" to 0.002" tolerance). Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The component maintains 70,000 psi tensile strength and operates effectively across the specified temperature range of -70° to 250°F.
