Professional Applications & Engineering Value
This M4 flat head screw delivers critical engineering solutions where high-strength fastening and space constraints intersect. The blue-dyed zinc-plated alloy steel construction provides superior corrosion protection for machinery, automotive assemblies, and outdoor equipment exposed to moisture and chemicals. With its Class 10.9 strength rating (120,000 PSI tensile strength) and Rockwell C32 hardness, it maintains integrity under vibration and heavy loads. The fully threaded design with coarse 0.7mm pitch enables quick installation in metals and plastics, while the 90° countersink angle creates seamless flush surfaces in precision applications. Meeting DIN 7991/ISO 10642 standards, this metric screw ensures dimensional consistency across European machinery and global industrial projects.
Specification Summary & Compliance
This fastener features M4 x 0.7mm coarse threading with Class 6g tolerance for precise fit, 30mm length with full threading, and 2.5mm hex drive compatibility. Manufacturing complies with DIN 7991/ISO 10642 specifications for dimensional accuracy and performance. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards.
