• Compliance with international standards including DIN 912/ISO 4762, ensuring consistent quality and interchangeability in global applications.

Professional Applications & Engineering Value

This M5 socket head cap screw is engineered to address critical challenges in industrial and mechanical assemblies where high strength, reliability, and corrosion resistance are paramount. The Class 12.9 alloy steel construction, combined with a blue zinc plating surface finish, provides excellent protection against rust and wear, making it ideal for use in automotive, machinery, and equipment manufacturing. The coarse metric thread (M5 x 0.8mm) and right-hand thread direction facilitate rapid installation and secure fastening in materials prone to vibration loosening. Its partially threaded design allows for precise clamping force distribution, reducing stress concentration and improving joint integrity. By meeting DIN 912/ISO 4762 specifications, this screw ensures dimensional accuracy and compatibility, delivering long-term performance in demanding environments.

Specification Summary & Compliance

This product adheres to precise dimensional tolerances, including a Class 5g6g thread fit per metric standards, and is manufactured in compliance with DIN 912 (identical to ISO 4762) for socket head cap screws. It also meets regulatory requirements such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and material restrictions are upheld for industrial use.
