  • Extended tip design with 8mm length for deeper penetration and secure fastening in demanding applications.
  • Durable external hex drive and 18mm head width provide excellent torque transmission and tool compatibility.
  • Enhanced wear resistance from Rockwell C20 hardness, extending service life in repetitive or high-vibration environments.
  • Compliance with DIN 561B standard guarantees dimensional accuracy and interchangeability for consistent quality.
  • Environmentally safe operation with RoHS 3 and REACH compliance, meeting strict regulatory requirements for industrial use.

Professional Applications & Engineering Value

This M16x2mm Class 8.8 steel hex set screw is engineered to address common industrial fastening challenges, such as component slippage and assembly instability. The coarse thread and extended tip design ensure deep, secure seating in materials like machinery frames, automotive parts, and heavy equipment, preventing loosening under vibration. Made from high-strength steel with a Rockwell C20 hardness, it resists deformation and wear, making it ideal for repetitive adjustments. The external hex drive allows for high-torque application with standard tools, streamlining maintenance and reducing downtime in production lines. Its compliance with DIN 561B ensures precise metric dimensions, facilitating seamless integration in global engineering projects.

Specification Summary & Compliance

This set screw features an M16x2mm coarse thread with Class 6g fit for standard tolerance, an extended tip diameter of 12 mm (tolerance: -0.27mm to 0), and a length of 60 mm. It meets DIN 561B manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for industrial use.
