Professional Applications & Engineering Value
This gray PVC hex head screw with 5/8"-11 UNC coarse thread delivers exceptional engineering value in demanding applications where metal fasteners would fail. The PVC plastic material provides inherent chemical resistance that prevents degradation from acids, alkalis, and other corrosive substances commonly encountered in plumbing, water treatment, and chemical processing facilities. The electrical insulation properties make it ideal for electrical enclosures, control panels, and applications where electrical isolation is critical. The external hex drive combined with coarse threading ensures quick installation and reliable performance in plastic, wood, and soft material applications, while the partially threaded design concentrates clamping force precisely where needed.
Specification Summary & Compliance
This 4" plastic hex head screw features precise Class 2A thread fit according to UNC coarse thread standards with 0.625" thread diameter and 1 1/2" minimum thread length. The fastener maintains dimensional accuracy with 7/8" head width and 31/64" head height for consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental responsibility while delivering reliable mechanical performance in industrial applications requiring plastic fasteners with specific chemical and electrical properties.
