Professional Applications & Engineering Value

Engineered for demanding industrial environments, these fiberglass hex head screws deliver exceptional performance where metal fasteners fail. The gray fiberglass construction provides inherent corrosion resistance, eliminating galvanic corrosion concerns in chemical processing, marine, and outdoor applications. With their 3/8"-16 UNC coarse thread configuration and external hex drive, these screws offer quick installation and reliable holding power in composite materials, plastics, and wood assemblies. The partially threaded design ensures precise clamping force control, while the temperature range of -60° to 190°F makes them ideal for HVAC systems, electrical enclosures, and automotive components exposed to thermal cycling. Their non-conductive properties and RoHS compliance further enhance their suitability for electronics and regulated industries.

Specification Summary & Compliance

This 3/8"-16 UNC coarse thread screw features Class 2A thread fit tolerance for reliable engagement and complies with inch system measurement standards. The partially threaded design provides 1½" minimum thread length on the 2" overall length configuration. Manufacturing adheres to RoHS 3 (2015/863/EU) compliance requirements, ensuring environmental safety in electronic and industrial applications. The fiberglass material composition meets industry standards for corrosion-resistant fasteners while maintaining dimensional stability across the specified temperature range.
