Professional Applications & Engineering Value

These fiberglass hex head screws with UNC coarse threading and Class 2A thread fit deliver exceptional engineering value in demanding applications. The gray fiberglass construction provides inherent corrosion resistance, eliminating galvanic corrosion concerns in marine, chemical processing, and electrical applications. The fully threaded design ensures maximum engagement strength, while the integrated flange distributes clamping force evenly, preventing surface damage and maintaining joint integrity. These non-conductive fasteners are particularly valuable in electrical enclosures, utility equipment, and applications requiring thermal stability across the -60° to 190°F operational range. The external hex drive accommodates standard tools for efficient installation in confined spaces.

Specification Summary & Compliance
