Professional Applications & Engineering Value
This M10 hex head screw delivers critical engineering solutions through its Class 10.9 high-tensile steel construction and DIN 931 compliance. The partially threaded design provides an unthreaded shank section that maintains clamping force in dynamic load applications, while the coarse metric thread (1.5mm pitch) ensures rapid assembly and superior vibration resistance. The external hex drive accommodates high torque applications common in heavy machinery, structural steel connections, and industrial equipment manufacturing. With Rockwell C32 hardness, this black steel fastener withstands repetitive stress cycles without deformation, making it ideal for automotive, construction, and manufacturing sectors where high-strength metric bolts are essential for safety-critical assemblies.
Specification Summary & Compliance
Manufactured to DIN 931 standards with Class 6g thread tolerance ensuring precise fitment in metric applications. The 240mm length features 45mm minimum thread length with right-hand coarse threading (M10x1.5mm). Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming suitability for international industrial supply chains. Class 10.9 strength certification guarantees consistent performance across batch productions.
