Professional Applications & Engineering Value
These M8 hex head screws with 1.25mm coarse pitch threading deliver critical performance advantages in demanding industrial settings. The CU2/CU3 brass material provides inherent corrosion resistance, eliminating galvanic compatibility issues in electrical components, marine hardware, and plumbing systems. The fully threaded metric design ensures maximum thread contact in thin materials and blind holes, while the external hex drive enables high-torque installation without cam-out damage. Engineered to ISO 4017/DIN 933 standards with Class 6g thread fit, these fasteners maintain dimensional consistency across production runs, reducing assembly time and improving manufacturing efficiency in automated environments.
Specification Summary & Compliance
Manufactured to exact ISO 4017/DIN 933 specifications with Class 6g thread tolerance for precision fit. The M8 x 1.25mm coarse thread configuration provides optimal engagement in standard applications. Full compliance with RoHS 3 (2015/863/EU) regulations under exemption 6(c) for lead in copper alloys. Mechanical properties include Rockwell B55 hardness and 50,000 psi tensile strength, validated through quality control processes.
