  • Superior durability and wear resistance thanks to high-strength alloy steel construction and Rockwell C45 hardness.
  • Reliable and precise engagement ensured by the Class 6g thread fit and coarse M6 x 1 mm thread for easy assembly and vibration resistance.
  • Optimized for confined spaces with a headless and hex drive design, allowing installation in tight areas with standard tools.
  • Guaranteed mechanical performance and interchangeability, manufactured to meet DIN 915 and ISO 4028 standards.
  • Safe for various industries with full compliance to RoHS 3 and REACH environmental regulations.
  • Consistent dimensional accuracy with precise tip length and diameter tolerances for repeatable, high-quality results.

Professional Applications & Engineering Value

This M6 set screw is engineered to solve critical fastening challenges in industrial settings where reliability is non-negotiable. Made from alloy steel and heat-treated to a Rockwell C45 hardness, it resists shear and deformation under high stress. The extended tip and coarse metric thread provide superior bite and clamping force, preventing loosening in vibrating machinery, automotive assemblies, and precision equipment. Its headless, hex drive design allows flush mounting, making it ideal for set screw applications in shafts, collars, and gears where space is limited and a secure, tamper-resistant hold is essential. Fully compliant with DIN 915 and ISO 4028, it ensures consistent performance and easy sourcing for global engineering projects.

Specification Summary & Compliance

This set screw features an M6 x 1 mm coarse metric thread with a Class 6g tolerance for precise fit. Dimensions include a 35 mm length, extended tip length of 3.25 mm (-0.25mm to 0 tolerance), and tip diameter of 4 mm (-0.3mm to 0 tolerance). It is manufactured from alloy steel with a hardness of Rockwell C45 and complies with DIN 915 (equivalent to ISO 4028), RoHS 3 (2015/863/EU), and REACH (EC 1907/2006) regulations, ensuring environmental safety and mechanical reliability.
