Professional Applications & Engineering Value
Engineered for demanding industrial fastening applications, these M8 hex head screws combine black-phosphate steel construction with Class 10.9 strength to solve critical engineering challenges. The flanged design distributes clamping force evenly, preventing surface damage while eliminating washer requirements in machinery assembly, automotive components, and structural frameworks. The fully threaded configuration with coarse pitch metric threading ensures maximum thread engagement in both thick materials and vibration-prone applications. With 150,000 psi tensile strength and Rockwell C32 hardness, these metric screws maintain integrity under extreme loads while the corrosion-resistant black-phosphate surface treatment protects against industrial atmospheres and chemical exposure.
Specification Summary & Compliance
These M8 x 1.25mm hex head screws feature Class 6g thread fit tolerance and comply with ISO 898-1 DIN 6921 manufacturing specifications. The fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. With 22mm length and 18mm flange diameter, these screws maintain dimensional accuracy per international metric standards for reliable interchangeability.
