Professional Applications & Engineering Value

These PVC hex head screws are engineered to address critical challenges in industries requiring chemical resistance and electrical insulation. The gray PVC plastic construction prevents degradation from exposure to acids, alkalis, and moisture, making them perfect for chemical processing, water treatment, and marine applications. Their non-conductive properties ensure safety in electrical enclosures, control panels, and telecommunications equipment, reducing risks of short circuits. The 1/2"-13 UNC coarse thread and Class 2A thread fit provide fast, reliable engagement in plastics and soft metals, while the external hex drive simplifies maintenance in tight spaces. Ideal for OEMs and MRO professionals, these screws offer a durable, compliant solution that enhances equipment longevity and operational safety.

Specification Summary & Compliance
