Professional Applications & Engineering Value

These fiberglass hex head screws deliver exceptional value in applications where metal fasteners fail. The gray fiberglass construction provides inherent resistance to chemicals, moisture, and electrical conductivity, making them ideal for electrical enclosures, chemical processing equipment, and marine applications. The 3/4"-10 UNC coarse thread configuration ensures rapid installation and superior holding power in composite materials and soft substrates. With their temperature resistance from -60° to 190°F, these screws maintain dimensional stability and mechanical properties in environments where thermal cycling would compromise metal alternatives. The external hex drive allows for high-torque installation using standard tools, while the partial threading prevents material damage in clearance sections.

Specification Summary & Compliance

This hex head screw features precision UNC coarse threads with Class 2A thread fit for consistent engagement and reliable performance. The 3/4"-10 thread size and 2 1/2" length provide standardized dimensions for interchangeability. Manufacturing complies with RoHS 3 (2015/863/EU) environmental regulations, ensuring restriction of hazardous substances. The right-hand thread direction and partially threaded design follow industry standards for predictable performance across industrial applications.
