Professional Applications & Engineering Value

This fiberglass hex head screw delivers exceptional value in corrosive and electrically sensitive environments where metal fasteners would fail. The gray fiberglass material provides inherent resistance to chemicals, moisture, and galvanic corrosion while maintaining structural integrity across a wide temperature range from -60° to 190°F. The flanged design eliminates the need for separate washers, distributing clamping force evenly and preventing surface damage. With UNC coarse threads and Class 2A thread fit, these screws offer reliable engagement in fiberglass, composite, and soft material applications common in electrical enclosures, chemical processing equipment, and marine installations. The external hex drive with substantial head width ensures secure tool engagement during high-torque installation.

Specification Summary & Compliance

This 1/2"-13 UNC hex head screw features precise Class 2A thread fit tolerances with coarse thread spacing for optimal performance in various materials. The fastener measures 3/4" in length with a 1 1/16" flange diameter and is fully threaded for maximum utility. Manufactured to inch system specifications, this product is RoHS 3 (2015/863/EU) compliant, meeting stringent environmental regulations for hazardous substance restrictions in industrial applications.
