Professional Applications & Engineering Value

Engineered for precision-driven industries, these M5 pan head screws deliver exceptional performance in automotive, electronics, and machinery assemblies. The zinc-plated steel material provides a robust barrier against oxidation, crucial for maintaining structural integrity in environments exposed to moisture or chemicals. With a coarse 0.8mm thread pitch and JIS drive style, these screws enable rapid installation and high torque transmission, reducing assembly time while minimizing strip-out risks. The fully threaded design ensures uniform stress distribution, preventing joint loosening under vibration—a common challenge in industrial equipment. Compliant with JIS B 1111, these fasteners offer reliable standardization for OEMs and maintenance teams seeking repeatable, secure connections in metric-based systems.

Specification Summary & Compliance

This screw features an M5 x 0.8mm coarse thread with Class 6g tolerance per ISO metric standards, ensuring precise fit. The 8mm length maintains a tight tolerance of -0.15 to 0.15 mm for consistent application. Manufacturing adheres to JIS B 1111 specifications for dimensional and mechanical properties. Compliance with RoHS 3 (2015/863/EU) confirms the absence of restricted hazardous substances, supporting sustainable procurement practices.
