• Superior corrosion resistance from the black-oxide coating, extending service life in harsh industrial environments.
• Precise torque application enabled by the 5 mm hex socket drive and standard socket head profile, reducing tool slippage and assembly errors.
• Optimized thread engagement with M6 x 1 mm coarse threads and Class 5g6g fit, providing secure fastening and vibration resistance.
• Versatile partial threading allowing for adjustable clamping force and ease of alignment in diverse assembly setups.
• High hardness of Rockwell C37, minimizing wear and deformation during repeated use.
• Compliance with international standards including DIN 912/ISO 4762, ensuring interchangeability and quality assurance.

Professional Applications & Engineering Value

This M6 socket head cap screw is engineered to address critical challenges in heavy-duty machinery, automotive systems, and precision equipment. The black-oxide alloy steel construction combats rust and chemical exposure, ideal for outdoor or humid settings. With a coarse thread pitch of 1 mm and Class 5g6g thread fit, it resists loosening under dynamic loads, while the partially threaded design concentrates strength where needed. Its high tensile strength and Rockwell C37 hardness ensure it withstands extreme pressures without failure, making it a top choice for industrial fasteners requiring longevity and reliability in demanding applications.

Specification Summary & Compliance

The screw adheres to DIN 912/ISO 4762 specifications, with precise Class 5g6g thread fit for metric coarse threading. It is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence for global industrial use.
