Professional Applications & Engineering Value

This M10 hex head screw delivers critical engineering solutions where high tensile strength and reliable fastening are paramount. The Class 10.9 steel construction with Rockwell C32 hardness provides exceptional resistance to shear forces and permanent deformation in structural applications, machinery assembly, and heavy equipment manufacturing. The partially threaded design allows for both secure clamping force in the threaded section and clearance in the smooth shank area, preventing galling in precision assemblies. With coarse metric threading and external hex drive, installation becomes significantly more efficient in high-volume production environments while maintaining consistent torque values. These industrial screws are engineered to withstand vibration, dynamic loads, and harsh operating conditions common in construction, automotive, and manufacturing sectors.

Specification Summary & Compliance

This metric hex head screw features precise M10 x 1.5mm coarse threading with Class 6g thread fit tolerance according to ISO standards, ensuring proper engagement with mating components. The 200mm length with 32mm minimum thread length provides versatile fastening capabilities. Manufacturing strictly follows DIN 931 specifications for dimensional accuracy and performance consistency. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for use in regulated industries and international markets.
