Key Features & Benefits at a Glance

  • Exceptional holding power thanks to alloy steel construction with Rockwell B67 hardness, resisting deformation under high stress.
  • Secure, non-slip fastening is achieved with the flat tip design, which minimizes component damage and prevents movement.
  • Reliable and quick installation is enabled by the coarse M8 x 1.25mm thread and simple slotted drive for easy tool access.
  • Precise and consistent fit is guaranteed by the Class 6g thread tolerance, ensuring compatibility and reducing assembly issues.
  • Proven industrial durability from compliance with DIN 551 and ISO 4766 standards, ensuring performance in rigorous applications.
  • Confident global sourcing with adherence to RoHS 3 and REACH environmental regulations, making them safe for various markets.
  • Space-saving headless design allows for flush mounting in assemblies where protrusion is not permissible.

Professional Applications & Engineering Value

This M8 set screw is engineered to solve critical fastening challenges in industrial settings. The alloy steel material and Rockwell B67 hardness provide the necessary strength to prevent stripping and maintain clamp load in high-vibration environments, such as machinery, automotive sub-assemblies, and precision equipment. The flat tip offers a larger contact surface, distributing pressure evenly to minimize surface marring on shafts and collars. Combined with the right-hand coarse thread and Class 6g fit, it ensures rapid assembly and a secure, reliable hold that withstands dynamic operational stresses, reducing maintenance needs and downtime.

Specification Summary & Compliance

This metric set screw features an M8 x 1.25mm coarse thread with a Class 6g thread fit for standard tolerance. It is manufactured to meet DIN 551 and ISO 4766 specifications, ensuring dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
