Professional Applications & Engineering Value
These M4 nylon hex head screws provide critical solutions for industries where metal fasteners fail. The black nylon plastic material offers inherent corrosion resistance, making them perfect for humid, chemical-exposed, or marine settings without protective coatings. Their non-conductive nature prevents electrical shorts, essential in electrical enclosures, PCB mounting, and automotive wiring systems. The fully threaded metric coarse pitch and Class 6g thread fit deliver superior holding power and ease of assembly, reducing installation time. With a temperature range of -40° to 185°F, they maintain integrity in both freezing and moderately high-heat environments, ideal for outdoor equipment, consumer appliances, and industrial machinery requiring lightweight, durable plastic fasteners.
Specification Summary & Compliance
This screw adheres to metric system standards with M4 thread size, 0.7mm coarse pitch, and Class 6g thread fit for precise dimensional accuracy. It features a fully threaded 16mm length, 7mm hex head width, and 3mm head height for consistent performance. The product is manufactured in compliance with RoHS 3 (2015/863/EU), ensuring it is free from hazardous substances and suitable for global electronic and industrial applications.
