Professional Applications & Engineering Value
This M4 socket head cap screw in 360 brass addresses critical engineering challenges in industrial settings where corrosion resistance and non-magnetic properties are essential. The fully threaded design with Class 6g thread fit ensures reliable fastening in precision equipment, electrical enclosures, and marine applications where steel fasteners would corrode or interfere with sensitive electronics. The hex socket drive provides superior torque transmission compared to standard screw heads, preventing cam-out during installation in confined spaces. With its coarse thread pitch of 0.7mm, this metric socket screw offers rapid assembly while maintaining vibration resistance in dynamic applications. The combination of 50,000 psi tensile strength and Rockwell B78 hardness makes it suitable for mechanical assemblies requiring both durability and corrosion protection without compromising structural integrity.
Specification Summary & Compliance
This socket head cap screw features precise M4 x 0.7mm threading with Class 6g tolerance per ISO metric standards, ensuring compatibility with standard mating components. Manufactured to DIN 912/ISO 4762 specifications for dimensional accuracy and performance reliability. The product maintains compliance with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys and meets REACH (EC 1907/2006) requirements as of January 17, 2023, confirming its suitability for regulated industrial applications.
