Professional Applications & Engineering Value

Engineered for industrial applications requiring reliable metric fastening solutions, these M4 pan head screws address critical challenges in machinery assembly, electrical enclosures, and automotive components. The zinc-plated steel material provides essential corrosion resistance against moisture and chemicals, while the coarse thread pitch (0.7mm) prevents cross-threading and speeds up high-volume production. With full threading and JIS drive compatibility, they ensure consistent clamping force and tool engagement, reducing installation errors in industrial screw applications where vibration resistance and long-term performance are paramount.

Specification Summary & Compliance

This M4 x 0.7mm x 16mm screw maintains precise length tolerance of -0.15 to 0.15 mm and Class 6g thread fit per metric standards. Manufacturing follows JIS B 1111 specifications for dimensional consistency, and the product is fully RoHS 3 (2015/863/EU) compliant, meeting international environmental regulations for hazardous substance restrictions.
