Professional Applications & Engineering Value
These Class 10.9 rounded head screws deliver exceptional engineering value in heavy-duty industrial applications where vibration resistance and structural integrity are paramount. The zinc-plated alloy steel construction provides superior corrosion protection for machinery, automotive assemblies, and construction equipment exposed to demanding environmental conditions. The combination of M8 coarse threading and flanged design ensures rapid installation while distributing clamp load effectively across wider surfaces. With Rockwell C32 hardness and precise Class 6h thread fit, these metric fasteners prevent stripping and maintain torque integrity in high-stress applications, making them ideal for structural frameworks, industrial machinery, and equipment manufacturing where reliability cannot be compromised.
Specification Summary & Compliance
This M8 x 1.25mm metric screw features precise Class 6h thread tolerance with 40mm overall length and 28mm minimum thread engagement. Manufactured to ISO 7380-2 specifications with partial threading and 17.8mm flange diameter. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across international markets. The Class 10.9 strength rating guarantees consistent performance meeting industrial fastening requirements.
