Professional Applications & Engineering Value
This M18 hex head screw delivers critical engineering solutions for industrial assembly challenges where vibration resistance and structural integrity are paramount. The Class 8.8 strength grade combined with Rockwell C21 hardness provides exceptional resistance to shear forces and mechanical stress in heavy machinery, structural steel connections, and equipment manufacturing. The fine 1.5mm thread pitch offers superior clamping force distribution, preventing loosening under dynamic loads. The partially threaded design concentrates strength where needed most while the zinc plating ensures long-term corrosion protection in harsh environments. These metric hex screws are engineered to maintain precise tolerances throughout their service life, making them ideal for automotive, construction, and industrial equipment applications requiring reliable, high-strength fastening solutions.
Specification Summary & Compliance
Manufactured to ISO 8765 specifications with dimensional compliance to DIN 960 standards. Features Class 6h thread fit precision for consistent mating with corresponding nuts. The 100mm length with 42mm minimum thread length provides optimal engagement. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand thread configuration with external hex drive ensures compatibility with standard industrial tools and installation procedures.
