Professional Applications & Engineering Value
These fiberglass hex head screws are engineered to address common industrial challenges such as corrosion, electrical conductivity, and temperature extremes. The gray fiberglass material provides inherent electrical insulation, making them perfect for electrical enclosures, marine equipment, and chemical processing plants where metal fasteners would fail. The UNC coarse thread and Class 2A thread fit ensure quick assembly and reliable hold in fiberglass-reinforced plastics or composite materials. With a flanged design, they distribute pressure evenly, reducing surface damage and maintaining integrity under high vibration conditions. Ideal for industrial and commercial applications requiring durable, non-conductive, and RoHS compliant fastening solutions.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a 3/8"-16 thread size and Class 2A thread fit for precise dimensional accuracy. It features a partial thread with a minimum length of 2" and a total length of 3". The product is manufactured to meet RoHS 3 (2015/863/EU) compliance, ensuring it is free from hazardous substances, and is suitable for applications demanding corrosion resistance and electrical insulation without compromising on mechanical performance.
