Professional Applications & Engineering Value
This M4 socket head cap screw is engineered to address common industrial challenges, such as corrosion and mechanical failure. The silver-plated 18-8 stainless steel material offers excellent resistance to rust and oxidation, extending service life in humid or chemical-exposed settings. Its metric coarse thread (M4 x 0.7mm) and Class 6g thread fit facilitate quick installation with reduced cross-threading risks, while the high vacuum rating ensures integrity in aerospace, electronics, and precision machinery. The combination of 70,000 psi tensile strength and a compact 8 mm length makes it a reliable choice for high-stress, space-constrained applications, enhancing overall assembly reliability.
Specification Summary & Compliance
This fastener adheres to DIN 912 / ISO 4762 specifications, ensuring precise dimensions including a Class 6g thread fit for metric coarse threading. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances. The manufacturing process maintains tight tolerances as per international standards, supporting consistent performance in industrial and technical applications.
