• Full regulatory compliance meeting DIN 7991 specifications, RoHS 3, and REACH standards for global industrial applications

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M8 flat head screws deliver exceptional performance in machinery assembly, structural frameworks, and heavy equipment manufacturing. The zinc-plated alloy steel construction provides superior corrosion protection while maintaining the high tensile strength required for critical joints. The fully threaded metric design with coarse pitch ensures maximum thread engagement in various materials, from steel to aluminum composites. The 90° countersink angle and flat head profile allow for flush mounting in precision applications where surface clearance is limited. These Class 12.9 screws are particularly valuable in applications requiring repeated disassembly and reassembly, as the Rockwell C39 hardness maintains thread integrity through multiple cycles. The hex drive configuration enables high-torque installation without cam-out, making them ideal for automated assembly systems and maintenance operations where reliability is paramount.

Specification Summary & Compliance

This metric flat head screw features precise M8 x 1.25mm coarse threading with Class 5g6g thread fit tolerance according to ISO standards. Manufacturing complies with DIN 7991 specifications for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety. With fully threaded design and standardized 90° countersink angle, these screws ensure consistent performance across industrial applications while maintaining compliance with international quality and environmental standards.
