Professional Applications & Engineering Value
These M12 hex flange screws deliver exceptional engineering value where vibration resistance and structural integrity are critical. The black corrosion-resistant coated steel construction protects against environmental degradation in outdoor equipment, agricultural machinery, and automotive assemblies. The integrated flange design provides superior clamping force distribution, preventing surface damage while eliminating loose washers in high-vibration applications. With Class 8.8 strength rating and coarse metric threading, these fully threaded screws maintain secure fastening in structural frames, heavy-duty enclosures, and industrial equipment where disassembly cycles are frequent. The external hex drive accommodates standard tools for efficient maintenance in confined spaces.
Specification Summary & Compliance
Manufactured to DIN 6921 specifications with Class 6g thread tolerance ensuring precise dimensional accuracy. The M12x1.75 coarse thread configuration provides optimal engagement in various materials. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for industrial fastener applications. Mechanical properties include Rockwell C22 hardness and 110,000 psi tensile strength as specified for Class 8.8 strength grade fasteners.
