Professional Applications & Engineering Value

Engineered for challenging environments where metal fasteners fail, these PEEK plastic socket head cap screws solve critical engineering problems in electrical insulation, chemical exposure, and thermal management applications. The beige PEEK material maintains dimensional stability across extreme temperature fluctuations from -50° to 500°F, preventing the thermal expansion issues common in metallic alternatives. With their 3/8"-16 UNC coarse threads and Class 2A thread fit, these screws provide reliable fastening in plastic assemblies, electronic enclosures, and semiconductor equipment where corrosion resistance and non-conductive properties are essential. The fully threaded design ensures maximum engagement in deep-tapped holes, while the standard socket head profile accommodates standard hex tools for consistent installation torque.

Specification Summary & Compliance

These socket head cap screws feature precision 3/8"-16 UNC coarse threads with Class 2A thread fit tolerance for consistent engagement. Manufacturing conforms to ASME B18.3 specifications ensuring dimensional accuracy and interchangeability. The screws maintain full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical safety. Additional certifications include UL 94 V-0 flammability rating for fire safety in electrical applications.
