• Versatile 180mm length with 38mm minimum thread length accommodating various material thicknesses in construction and industrial applications

Professional Applications & Engineering Value

This M14 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 withstands extreme vibrational forces and dynamic loads common in heavy machinery, structural steel connections, and industrial equipment assembly. The partially threaded design provides an unthreaded bearing surface that resists shear forces while the threaded portion maintains precise clamping pressure. With coarse metric threading and Class 6g tolerance, installation is accelerated in steel frameworks, construction projects, and manufacturing applications where time efficiency matters. The external hex drive ensures compatibility with standard tools while the black finish offers additional corrosion protection in challenging environments.

Specification Summary & Compliance

Manufactured to DIN 931 specifications with Class 6g thread fit ensuring precise dimensional accuracy and interchangeability. The fastener meets Class 10.9 strength requirements with verified 150,000 psi tensile strength and Rockwell C32 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for regulated industries and international projects requiring certified components.
