Professional Applications & Engineering Value

This nylon plastic socket head cap screw delivers critical performance advantages where metal fasteners fail. The non-conductive properties make it ideal for electrical enclosures, control panels, and electronic assemblies where insulation is paramount. Its inherent corrosion resistance solves degradation issues in marine, chemical processing, and outdoor applications without requiring additional coatings. The 1/4"-20 UNC coarse threads with Class 2A fit provide quick installation and reliable holding power in plastic, composite, and soft material assemblies. The hex socket drive enables high-torque installation in confined spaces, while the temperature stability ensures consistent performance from industrial freezers to heated equipment compartments.

Specification Summary & Compliance

Manufactured to UNC thread standards with Class 2A thread fit for consistent dimensional accuracy and reliable engagement. Features 1/4"-20 coarse threads with right-hand direction and fully threaded design. Compliant with RoHS 3 (2015/863/EU) regulations, ensuring environmental safety and restricted substance compliance. The inch system measurements include 1/2" length, 3/8" head diameter, and 3/16" hex drive for standardized compatibility across industrial applications.
