Professional Applications & Engineering Value
This M3 socket head cap screw is specifically engineered for high vacuum applications where even minor outgassing can compromise system performance. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, which is critical in sensitive environments like semiconductor manufacturing, analytical instrumentation, and aerospace systems. The integrated vented screw design, with its 1 mm vent diameter, actively prevents air and moisture entrapment, a common failure point in vacuum seals. Combined with a Rockwell B70 hardness and fully threaded coarse thread (0.5 mm pitch) profile, it delivers robust clamping force and vibration resistance, solving the dual challenges of maintaining vacuum integrity and providing reliable mechanical strength in precision assemblies.
Specification Summary & Compliance
This metric screw features an M3 x 0.5 mm thread with a Class 6g thread fit per ISO standards, ensuring precise dimensional tolerances. The manufacturing and material specifications strictly adhere to DIN 912 / ISO 4762. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial markets.
