Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M5 metric screws address critical challenges in machinery assembly, marine equipment, and chemical processing systems. The 316 Stainless Steel material combined with a black oxide finish provides exceptional resistance to pitting and chloride-induced corrosion, significantly extending service life in aggressive environments. The flat head design with a 100° countersink angle ensures a flush surface finish, eliminating protrusions that could interfere with moving parts or aesthetic requirements. With a Class 6g thread fit and coarse threading, these screws deliver reliable clamping force and vibration resistance, reducing maintenance frequency and downtime in high-stress assemblies.
Specification Summary & Compliance
This fully threaded screw features M5 x 0.8 mm metric coarse threads with Class 6g tolerance for precision fit. Dimensional accuracy includes a head diameter tolerance of -0.127 to 0.127 mm. Manufactured in compliance with ASTM A276 material specifications, and fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe industrial use.
