Professional Applications & Engineering Value
These fiberglass hex head screws provide critical solutions for industries where metal fasteners fail. The gray fiberglass material offers inherent corrosion resistance without additional coatings, making them ideal for chemical processing, marine, and outdoor applications. Their electrical insulation properties prevent current conduction, essential in electrical enclosures, panel boxes, and utility applications. The UNC coarse thread design ensures rapid installation and superior pull-out resistance in various materials, while the external hex drive allows for high torque application with standard tools. With a temperature range of -60° to 190°F, these screws maintain structural integrity in both freezing and elevated temperature environments where thermal expansion would compromise metal fasteners.
Specification Summary & Compliance
This 1/4"-20 UNC coarse thread screw features Class 2A thread fit tolerances for consistent engagement and reliable performance. The fully threaded 1-1/2" length provides maximum thread contact throughout the fastener. Manufactured to meet RoHS 3 (2015/863/EU) compliance standards, ensuring environmental responsibility and global regulatory acceptance for industrial applications requiring non-metallic, corrosion-resistant fastening solutions.
