Professional Applications & Engineering Value
Engineered for demanding industrial environments, these M4 pan head screws address critical challenges in machinery assembly, electrical enclosures, and automotive components where vibration and corrosion are persistent concerns. The 18-8 stainless steel core with passivated finish provides exceptional resistance to oxidation and chemical exposure, extending service life in humid or corrosive settings. The integrated internal-tooth lock washer made from 410 stainless steel bites into mating surfaces, maintaining clamp load under cyclic stresses—effectively solving loosening issues in motors, conveyors, and structural frameworks. With fully threaded coarse metric threading and Phillips drive, installation is streamlined while ensuring high repeatability in automated or manual assembly lines.
Specification Summary & Compliance
This M4 x 0.7mm x 6mm screw adheres to ISO 7045 dimensional standards with Class 6g thread fit for precision assembly. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The passivated finish on both screw and washer enhances durability without compromising regulatory adherence.
