Professional Applications & Engineering Value
This M5 flat head screw is engineered to address critical challenges in corrosive and high-strength industrial settings. Made from 316 stainless steel with a passivated finish, it resists oxidation and chemical exposure in marine, chemical processing, and outdoor applications. The fully threaded metric coarse thread (M5 x 0.8mm) and Class 6g thread fit ensure precise alignment and reduced loosening in machinery, enclosures, and structural frameworks. Its flat head design with a standard profile enables seamless integration into countersunk holes, providing a smooth surface that prevents snagging and enhances safety. Ideal for B2B procurement in sectors requiring DIN 963 standard compliance, this fastener delivers durability and performance in demanding fastening solutions.
Specification Summary & Compliance
This product adheres to DIN 963 specifications, with a Class 6g thread fit ensuring metric dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for environmental and health safety. The screw features a right-hand thread with coarse spacing (0.8 mm pitch), fully threaded length of 20 mm, and is manufactured from 316 stainless steel with a passivated finish for enhanced corrosion resistance.
