Professional Applications & Engineering Value
Engineered for precision assemblies requiring non-conductive, chemically resistant fastening solutions, these glass-filled nylon socket head cap screws deliver exceptional performance where metal fasteners would cause electrical shorts or corrosion. The 6-32 UNC coarse thread with Class 2A fit provides secure mating in plastic and soft material applications, while the standard socket head profile with 7/64" hex drive ensures reliable torque transmission. Ideal for electrical enclosures, automotive components, and food processing equipment, these screws maintain dimensional stability across their -20° to 230°F operational range, solving thermal expansion challenges in temperature-cycling environments.
Specification Summary & Compliance
This 1/4" length socket head cap screw features 6-32 UNC coarse threading manufactured to Class 2A dimensional tolerances for consistent fit. The fully threaded design with right-hand direction follows standardized installation practices. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while maintaining the mechanical properties required for industrial applications.
