Professional Applications & Engineering Value
This fiberglass hex head screw with UNC coarse thread pattern delivers exceptional value in electrical, chemical processing, and marine applications where metal fasteners would corrode or conduct electricity. The gray fiberglass material provides inherent resistance to rust, chemicals, and UV degradation, while the fully threaded design ensures maximum grip length and holding power. The integrated flange distributes clamping force over a wider area, preventing surface damage and maintaining seal integrity in assembled components. These industrial screws are particularly valuable in applications requiring non-magnetic properties and consistent performance across the specified temperature range from -60° to 190°F.
Specification Summary & Compliance
This 3/8"-16 UNC coarse thread fastener features Class 2A thread fit per ANSI/ASME B1.1 standards, ensuring proper clearance and engagement in mating components. The screw is fully threaded with right-hand direction and includes a 51/64" flange diameter for enhanced load distribution. Manufactured to comply with RoHS 3 (2015/863/EU) regulations, this fastener contains no restricted hazardous substances, making it suitable for global industrial applications requiring environmental compliance.
