Professional Applications & Engineering Value

These M4 nylon plastic screws deliver exceptional engineering value where metal fasteners fail. The nylon material provides inherent corrosion resistance, making them ideal for humid, chemical, or marine environments where stainless steel might still corrode. The electrical insulation properties prevent galvanic corrosion and current leakage in electrical assemblies, electronic enclosures, and control panels. With fully threaded construction and Class 6g metric thread fit, these pan head screws ensure maximum thread engagement and vibration resistance in plastic components, automotive trim, and consumer products. The coarse 0.7mm pitch enables quick installation in soft materials without stripping, while the temperature range accommodates both indoor and outdoor applications without performance degradation.

Specification Summary & Compliance

This M4 x 0.7mm x 20mm nylon plastic screw features precision metric coarse threading with Class 6g thread fit tolerance according to ISO metric standards. The fully threaded design ensures consistent engagement along the entire 20mm length. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, guaranteeing restriction of hazardous substances. The pan head style with slotted drive provides standardized installation compatibility while maintaining the rounded head profile for aesthetic and safety considerations in finished applications.
