Professional Applications & Engineering Value
Engineered for demanding electrical and industrial applications, these M12 nylon hex head screws solve critical challenges where metal fasteners fail. The black nylon plastic construction provides inherent corrosion resistance and electrical insulation, eliminating short-circuit risks in control panels, enclosures, and electronic assemblies. With Class 6g thread precision and coarse metric threading, installation becomes faster and more reliable in plastic housings and composite materials, reducing stripping and improving vibration resistance. The temperature-resistant properties maintain structural integrity from freezing conditions to elevated heat exposures, making these fully threaded screws ideal for outdoor equipment, automotive components, and chemical processing installations where durability and safety are paramount.
Specification Summary & Compliance
This metric hex head screw features M12 x 1.75mm coarse thread with Class 6g tolerance for precision fit, fully threaded design, and dimensions of 40mm length with 18mm hex head. Manufactured to RoHS 3 (2015/863/EU) compliance standards, ensuring environmental safety and restriction of hazardous substances. The right-hand thread and external hex drive conform to standard metric fastener specifications for consistent performance in industrial applications.
