Professional Applications & Engineering Value
These M12 hex head screws with extra fine 1.25mm pitch deliver critical engineering advantages where standard coarse threads fall short. The Class 8.8 steel construction provides reliable performance in structural applications, machinery assembly, and heavy equipment where vibration resistance and load-bearing capacity are paramount. The zinc plated finish effectively combats corrosion in industrial environments, while the partially threaded design allows for precise clamping force distribution. With 110mm length and Rockwell C21 hardness, these metric screws solve common challenges in automotive, manufacturing, and construction applications where dimensional stability and repeated assembly/disassembly cycles are required. The external hex drive ensures quick installation with standard tools, reducing assembly time and labor costs.
Specification Summary & Compliance
This hex head screw features precise Class 6h thread fit according to ISO metric standards with M12 x 1.25mm extra fine pitch threading. Manufacturing complies with ISO 8765 (DIN 960) specifications, ensuring dimensional accuracy and performance reliability. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards, making it suitable for global industrial applications requiring strict regulatory adherence.
