Professional Applications & Engineering Value
This M4 flat head machine screw is engineered to solve critical fastening challenges in precision industries. Its 18-8 stainless steel material offers excellent resistance to rust and oxidation, making it suitable for electronics assembly, automotive components, and machinery exposed to moisture or mild chemicals. The metric coarse thread with a 0.7mm pitch and Class 6g thread fit ensures quick installation and high resistance to loosening under dynamic loads. The JIS drive style (No. 2) provides a secure tool engagement, reducing cam-out risks during high-torque applications. Combined with a fully threaded shank, this screw delivers uniform clamping force, preventing joint failure in demanding industrial environments.
Specification Summary & Compliance
This screw adheres to JIS B 1111 specifications, ensuring precise dimensional control for the M4 x 0.7mm metric coarse thread with a Class 6g thread fit. The flat head profile features a standard 90° countersink angle and is fully threaded along the 12mm length. It is manufactured from 18-8 stainless steel and is compliant with RoHS 3 (2015/863/EU) environmental regulations, confirming its suitability for use in regulated industries.
