Professional Applications & Engineering Value
These M4 pan head spanner drive screws are engineered to address common industrial challenges, such as corrosion in humid or chemical-exposed settings. Made from 18-8 stainless steel with a passivated finish, they resist oxidation and degradation, extending service life in machinery, electronics, and automotive assemblies. The coarse thread pitch (0.7mm) and Class 6g thread fit facilitate rapid installation while maintaining tight tolerances, reducing assembly time and minimizing loosening from vibrations. The drilled spanner drive ensures secure tool engagement, preventing stripping and enhancing safety in high-torque applications. Ideal for industrial screws in equipment requiring reliable, corrosion-resistant fasteners, these metric screws deliver consistent performance and reduce maintenance costs.
Specification Summary & Compliance
This screw features an M4 thread size with 0.7mm coarse pitch, fully threaded design, and Class 6g thread fit per metric standards for precise dimensional accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements. Manufactured from 18-8 stainless steel with a passivated finish, it meets industry specifications for hardness (Rockwell B85) and tensile strength (80,000 psi), supporting reliable use in regulated applications.
