Professional Applications & Engineering Value
These M14 hex head screws deliver critical engineering solutions for heavy machinery, structural assemblies, and industrial equipment where high tensile strength and vibration resistance are paramount. The Class 10.9 steel construction with Rockwell C32 hardness prevents thread deformation under extreme loads, while the coarse pitch threading (M14x2mm) enables faster assembly in tough materials. The external hex drive provides superior torque transmission compared to internal drive systems, reducing tool slippage and fastener damage. Fully compliant with DIN 933 standards, these fully threaded metric bolts maintain consistent clamping force in automotive, construction, and manufacturing applications where failure is not an option.
Specification Summary & Compliance
Manufactured to DIN 933 specifications with Class 6g thread tolerance ensuring precise fitment. The metric coarse pitch (M14x2mm) provides optimal thread engagement in various materials. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Class 10.9 strength rating corresponds to 150,000 psi minimum tensile strength with Rockwell C32 hardness for consistent performance across industrial applications.
