Professional Applications & Engineering Value

This fiberglass hex head screw delivers exceptional value in corrosive environments where metal fasteners would fail. The gray fiberglass material provides inherent resistance to chemicals, saltwater, and UV exposure while maintaining electrical insulation properties. The fully threaded UNC coarse thread design ensures maximum grip strength in composite materials and soft substrates, while the integrated flange distributes clamping force evenly, preventing surface damage and reducing assembly components. Engineered for industrial applications requiring non-conductive, non-magnetic fasteners, this external hex drive screw offers reliable performance in electrical enclosures, chemical processing equipment, and marine structures where temperature fluctuations and environmental factors challenge conventional fasteners.

Specification Summary & Compliance

This 1/2"-13 UNC hex head screw features precision Class 2A thread fit per Unified Thread Standard specifications, ensuring consistent engagement and proper clearances. The coarse thread spacing provides optimal performance in various materials while the 2" length and fully threaded design offer versatile fastening solutions. Manufactured to comply with RoHS 3 (2015/863/EU) regulations, this fastener meets stringent environmental standards while delivering reliable mechanical performance in demanding applications.
