S-91345A700 3/8"-16 x 1" Fiberglass Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to high-performance fiberglass construction, ideal for harsh chemical environments
• Excellent thermal stability with a wide operating range from -60° to 190°F, ensuring reliable performance in extreme temperatures
• Enhanced installation security provided by the external hex drive and flanged design, which distributes load and prevents pull-through
• Precise thread engagement with Class 2A thread fit for consistent, reliable fastening in industrial assemblies
• Robust mechanical strength from the coarse UNC thread and fully threaded shank, designed for high-load applications
• Environmental compliance assurance as a RoHS 3 compliant product, meeting strict regulatory standards for hazardous substances
• Streamlined assembly process with a standard 9/16" hex head for easy tool access and efficient installation

Professional Applications & Engineering Value

Engineered for demanding environments, these fiberglass hex head screws provide a non-conductive, non-magnetic alternative to metal fasteners where electrical isolation is critical. The flanged design eliminates the need for a separate washer, reducing part count and assembly time while providing a larger bearing surface to protect softer materials. With fully threaded UNC coarse threads and Class 2A thread fit, these screws deliver superior holding power in fiber-reinforced plastics, composites, and other industrial materials. The gray fiberglass construction maintains dimensional stability across the -60° to 190°F temperature range, making these RoHS compliant screws ideal for electrical enclosures, chemical processing equipment, and marine applications where corrosion resistance is paramount.

Specification Summary & Compliance

This 3/8"-16 UNC hex head screw features precise Class 2A thread fit tolerances according to Unified Thread Standard specifications. The fully threaded design with coarse thread spacing ensures optimal engagement in various materials. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, guaranteeing environmental safety and restricted substance compliance. The external hex drive with 9/16" head width provides standard tool compatibility for industrial applications.
