Key Features & Benefits at a Glance
- Superior holding power with cup point design that bites into mating surfaces to prevent component slippage
- Exceptional durability from Rockwell C45 hardness alloy steel construction, resisting wear in high-vibration applications
- Precise and reliable fastening ensured by the Class 5g6g thread fit, minimizing the risk of cross-threading
- High torque capability with the internal 6mm hex drive, allowing for secure installation with standard tools
- Optimized for quick assembly thanks to the coarse (1.75mm pitch) metric thread, reducing installation time
- Headless, flush-mount design provides a clean finish and is ideal for applications with limited space
- Guaranteed material integrity and environmental compliance with RoHS 3 and REACH regulations
Professional Applications & Engineering Value
This M12 set screw is engineered to solve critical fastening challenges in demanding industrial environments. The alloy steel construction, heat-treated to Rockwell C45 hardness, provides the necessary strength to resist loosening under continuous vibration and dynamic loads, a common failure point in machinery and equipment. The cup point tip concentrates pressure to create a permanent indentation, effectively locking components like gears, pulleys, and collars onto shafts without the need for additional locking devices. Manufactured to DIN 916 / ISO 4029 standards with a Class 5g6g thread fit, it guarantees dimensional accuracy and interchangeability, streamlining maintenance and parts replacement. This makes it an indispensable component for heavy-duty set screw applications in automotive, manufacturing, and power transmission systems.
Specification Summary & Compliance
This set screw conforms to the dimensional and tolerance requirements of DIN 916 and ISO 4029. The metric thread is M12 x 1.75mm with a Class 5g6g fit, ensuring precision for the external thread. The product is manufactured from alloy steel and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
