Professional Applications & Engineering Value

Engineered for demanding industrial fastening scenarios, these metric hex head screws solve critical challenges in electronics, machinery, and outdoor equipment. The black nylon plastic construction eliminates galvanic corrosion when joining dissimilar metals while providing inherent electrical insulation. With Class 6g thread precision and coarse 0.8mm pitch, these screws prevent cross-threading during high-volume assembly operations. The fully threaded M5 design ensures consistent clamping force across plastic housings, sheet metal, and composite materials. Ideal for temperature-sensitive applications from freezer components to automotive interiors, these RoHS compliant fasteners meet stringent regulatory requirements without compromising mechanical performance.

Specification Summary & Compliance

Manufactured to metric thread standards with M5x0.8mm coarse pitch and Class 6g tolerance for precise fit. Features 20mm length with fully threaded configuration and external hex drive (8mm head width). Complies with RoHS 3 (2015/863/EU) environmental regulations. Temperature rating spans -40° to 185°F for diverse operating conditions.
