Professional Applications & Engineering Value

These M12 hex head screws deliver exceptional engineering value in heavy-duty industrial applications where reliability is paramount. The Class 8.8 steel construction provides the necessary strength for structural connections in construction, machinery assembly, and equipment manufacturing. The zinc plating finish significantly extends service life in challenging environments by preventing rust and corrosion. With coarse metric threading (1.75mm pitch), these fasteners offer superior resistance to vibration loosening while enabling quicker installation compared to fine-thread alternatives. The partially threaded design allows for precise clamping force distribution, making them ideal for applications requiring both secure fastening and component alignment. Engineered to ISO 4014 and DIN 931 standards, these screws ensure perfect compatibility with existing metric fastener systems and tooling.

Specification Summary & Compliance

This M12 x 1.75mm hex head screw features precise Class 6h thread fit tolerance according to ISO metric standards, ensuring proper engagement with mating components. The fastener is manufactured to comply with ISO 4014 dimensional specifications and ISO 898 mechanical property requirements (equivalent to DIN 931). The product meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations regarding chemical safety. With a 75mm length and 30mm minimum thread length, this partially threaded screw maintains dimensional consistency across production batches for reliable performance in industrial applications.
