Professional Applications & Engineering Value

This M20 hex head screw delivers critical engineering solutions for heavy-duty industrial applications where failure is not an option. The Class 10.9 steel construction provides exceptional tensile strength that prevents bolt stretching and maintains clamp load in structural steelwork, machinery assembly, and construction projects. The partially threaded design concentrates threads where needed most, eliminating unnecessary threading in shank areas and providing superior resistance to vibrational loosening. Combined with the zinc yellow-chromate plating, these metric bolts offer extended service life in corrosive environments while the coarse thread pitch ensures rapid installation in both through holes and tapped applications. The external hex drive configuration allows for high torque application with common tools, making these high tensile strength screws ideal for maintenance, manufacturing, and infrastructure projects requiring reliable, long-lasting fastening solutions.

Specification Summary & Compliance

This metric hex head screw features precise M20x2.5 coarse threads with Class 6h thread fit tolerance for consistent engagement. The fastener maintains ISO 4014/DIN 931 specifications throughout manufacturing, ensuring dimensional accuracy and performance reliability. With a defined thread length of 46mm minimum on the 110mm overall length, the partially threaded configuration provides optimal clamping force distribution. The zinc yellow-chromate plating offers corrosion protection while maintaining compliance with RoHS and REACH environmental standards. Manufactured to exacting Class 10.9 strength requirements, this hex bolt delivers guaranteed mechanical properties for critical applications where specification adherence is paramount.
