Professional Applications & Engineering Value
These M8 hex head screws deliver exceptional engineering value in applications where corrosion resistance and mechanical reliability are critical. The CU2/CU3 brass construction provides inherent protection against oxidation and galvanic corrosion, making them ideal for marine equipment, plumbing systems, electrical enclosures, and chemical processing installations. The fully threaded metric coarse thread design with Class 6g fit ensures rapid assembly and vibration resistance, while the external hex drive allows for high-torque installation without stripping. With 50,000 psi tensile strength and Rockwell B55 hardness, these screws maintain clamping force in dynamic load conditions, preventing joint failure in machinery, structural frameworks, and industrial assemblies requiring repeated maintenance access.
Specification Summary & Compliance
This M8 x 1.25mm x 20mm hex head screw features Class 6g thread tolerance according to metric standards with coarse thread spacing. Manufacturing complies with ISO 4017 where identical to DIN 933 specifications, ensuring dimensional accuracy and mechanical properties. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(c) for lead in copper alloy, meeting environmental regulations for industrial use.
