Key Features & Benefits at a Glance
- Superior holding power with the cup point design that bites into mating surfaces for secure, vibration-resistant fastening
- Exceptional durability and wear resistance thanks to the Rockwell C45 hardened alloy steel construction
- Simplified installation and high torque capability with the 6mm internal hex drive, ideal for confined spaces
- Reliable and predictable thread engagement ensured by the Class 5g6g thread fit for consistent performance
- Quick assembly in a wide range of materials facilitated by the coarse (1.75mm pitch) metric thread
- Guaranteed dimensional interchangeability and quality through compliance with DIN 916 / ISO 4029 standards
- Safe for use in regulated environments as it is RoHS 3 and REACH compliant, containing no hazardous substances
Professional Applications & Engineering Value
This M12 set screw is engineered to solve critical challenges in industrial assembly and maintenance. The alloy steel material, hardened to Rockwell C45, provides the necessary strength to prevent stripping and deformation under high stress, making it ideal for permanently securing gears, pulleys, and collars onto shafts. The cup point concentrates force on a small area, creating a deep indentation for maximum resistance to loosening from vibration—a common failure point in machinery. Its headless design and hex drive allow for flush mounting in space-constrained applications. The coarse metric thread ensures rapid installation and reliable performance in softer materials or where frequent disassembly is not required, delivering long-term industrial reliability.
Specification Summary & Compliance
This set screw conforms to the dimensional and tolerance specifications of DIN 916 / ISO 4029. The M12x1.75mm right-hand thread is manufactured to a Class 5g6g fit, ensuring precise thread engagement and interchangeability. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free from restricted hazardous substances for safe use in various industrial and international markets.
