Professional Applications & Engineering Value
These M3 x 0.5 mm Class 10.9 black-oxide alloy steel hex screws deliver critical engineering solutions for industrial applications requiring high tensile strength and corrosion resistance. The fully threaded coarse pitch design ensures rapid assembly and secure fastening in machinery, automotive components, and electronic enclosures where vibration resistance is paramount. The rounded button head profile provides a low-profile finish while the Rockwell C32 hardness maintains thread integrity under repeated stress cycles. Engineered to prevent galvanic corrosion and withstand harsh operating conditions, these metric hex screws offer reliable performance in manufacturing equipment, precision instruments, and structural assemblies where failure is not an option.
Specification Summary & Compliance
This M3 x 0.5 mm coarse pitch screw features Class 6g thread tolerance and full compliance with ISO 7380 dimensional standards. The fastener meets Class 10.9 strength requirements with 140,000 psi tensile strength and Rockwell C32 hardness. Manufacturing and material composition adhere to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The right-hand threaded design with standardized 2 mm hex drive provides consistent performance in automated and manual assembly processes.
