• Superior corrosion resistance and electrical insulation due to durable fiberglass construction
• Maximum torque application enabled by external hex drive and Class 2A coarse UNC threading
• Enhanced load distribution and stability through integrated flange design
• Full threading coverage for consistent holding power across the entire 2 1/2" length
• RoHS 3 compliance ensuring environmental safety and regulatory adherence
• Easy identification and installation with standardized gray color and right-hand thread direction

Professional Applications & Engineering Value

These fiberglass hex head screws deliver critical solutions for industrial applications where metal fasteners fail. The fiberglass material provides inherent corrosion resistance and electrical insulation, making them ideal for electrical enclosures, chemical processing equipment, and marine environments. With a temperature range of -60°F to 190°F, they maintain structural integrity in thermal cycling conditions where expansion/contraction would compromise metal components. The UNC coarse threading and external hex drive combine for rapid installation and high torque capability, while the flanged design eliminates need for separate washers. These features make them essential for industrial applications requiring non-conductive, non-corrosive fastening solutions.
