Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M18 hex head screws deliver exceptional performance where high tensile strength and reliable fastening are critical. The Class 10.9 steel construction with Rockwell C32 hardness ensures superior resistance to vibration loosening and mechanical stress in construction equipment, machinery assembly, and structural frameworks. The coarse metric thread (M18x2.5mm) provides rapid installation in cast iron, steel plates, and other robust materials, while the partial threading design prevents thread damage during repeated disassembly. External hex drive enables high-torque application with standard tools, making these DIN 931 compliant fasteners ideal for maintenance, manufacturing, and engineering projects requiring consistent performance under extreme conditions.
Specification Summary & Compliance
This metric hex head screw features precise Class 6g thread fit tolerance ensuring proper engagement and alignment. Manufactured to DIN 931 specifications with 75mm length, 37mm minimum thread length, and right-hand coarse threading. The fastener meets international regulatory standards including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, guaranteeing environmental responsibility and material safety for global industrial applications.
