• Versatile partial threading allowing precise clamping force control across various material thicknesses

Professional Applications & Engineering Value

These M10 hex head screws deliver critical engineering solutions where vibration resistance and structural integrity are paramount. The black-phosphate steel construction provides essential corrosion protection for outdoor equipment, machinery frames, and automotive assemblies exposed to harsh conditions. The Class 10.9 strength rating ensures reliable performance in high-stress applications like structural steel connections, heavy machinery, and industrial platforms. The flanged design eliminates washer requirements while distributing clamp load effectively, reducing assembly time and potential failure points. With partial threading and coarse metric thread pitch, these screws maintain secure fastening in vibrating environments while accommodating various material thicknesses in construction and manufacturing applications.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 6g thread tolerance ensuring consistent fit and performance. Complies with ASME B18.2.3.9M specifications for dimensional accuracy and mechanical properties. Meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance. The metric coarse threading (M10 x 1.5mm) and 90mm length with 26mm minimum thread length provide standardized compatibility across industrial applications requiring high-strength fastening solutions.
