Professional Applications & Engineering Value

This fiberglass hex head screw with a flanged design addresses common industrial challenges like corrosion, thermal expansion, and assembly efficiency. The gray fiberglass material offers excellent non-conductive and non-magnetic properties, making it suitable for electrical enclosures, chemical processing equipment, and marine applications where metal fasteners fail. Its UNC coarse threads and Class 2A thread fit ensure quick, secure fastening in composite or soft materials, reducing installation time and minimizing strip-out risks. The integrated flange distributes clamping force evenly, enhancing joint integrity under vibration—ideal for machinery, HVAC systems, and structural supports in high-temperature or corrosive settings, while RoHS compliance supports sustainable manufacturing practices.

Specification Summary & Compliance

This screw features a 1/2"-13 UNC coarse thread with Class 2A thread fit for standard dimensional accuracy and ease of assembly. It is fully threaded, right-hand direction, and includes a hex head with external drive for tool compatibility. Manufactured from fiberglass, it adheres to RoHS 3 (2015/863/EU) compliance, ensuring it is free from hazardous substances for use in industrial and electronic applications.
