Professional Applications & Engineering Value

This M5 flat head screw delivers critical engineering advantages in demanding applications. The 316 Stainless Steel material provides outstanding resistance to chlorides and acidic environments, making it ideal for marine equipment, chemical processing plants, and food processing machinery where corrosion causes premature failure. The fully threaded design with coarse 0.8mm pitch ensures maximum grip length and faster installation in various substrates. The undercut flat head profile allows for complete flush mounting without protrusion, while the hex drive accommodates high installation torque without stripping. Combined with the passivated finish, these metric screws maintain integrity in temperature-variable conditions and humid operations, reducing maintenance frequency and replacement costs in industrial fastening systems.

Specification Summary & Compliance

This fastener maintains precise dimensional control with Class 6g thread fit per metric standards and head diameter tolerance of -0.127 to 0.127 mm. Manufacturing follows metric threading specifications with M5 x 0.8mm coarse thread profile and 100° countersink angle. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial distribution and use.
