Professional Applications & Engineering Value
Engineered for demanding applications, this M4 metric screw solves critical challenges in aerospace, automotive, and electronics assembly. The A286 Stainless Steel material offers excellent resistance to oxidation and corrosion at elevated temperatures, preventing fastener failure. The Torx button head and T20 drive work in tandem to deliver high torque application without cam-out, protecting the drive recess and component surfaces. The coarse 0.7mm pitch and Class 6g thread ensure rapid assembly and a secure fit in tapped holes, reducing the risk of cross-threading. This combination of high-strength and precision makes it an indispensable industrial fastener for applications where vibration resistance and reliability are non-negotiable.
Specification Summary & Compliance
This fastener adheres to metric thread standards with an M4 x 0.7mm coarse pitch and a Class 6g thread fit for manufacturing precision. The mechanical properties are defined by a Rockwell C31 hardness and 140,000 psi tensile strength. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent international standards for restricted substances and chemical safety.
