Key Features & Benefits at a Glance
- Superior holding power with cup point design that bites into materials for secure, vibration-resistant fastening.
- Exceptional durability provided by alloy steel construction and Rockwell C45 hardness, resisting wear and deformation under load.
- Precise and reliable installation enabled by the 0.9 mm hex drive, allowing for high torque application in confined spaces.
- Optimized for coarse threading (0.4 mm pitch) for faster assembly and robust performance in a wide range of materials.
- Guaranteed dimensional accuracy with Class 5g6g thread fit, ensuring consistent performance and interchangeability.
- Broad industry compliance meeting DIN 916 / ISO 4029 standards for quality and RoHS 3 / REACH regulations for environmental safety.
- Versatile headless design ideal for applications where a flush surface is required without protruding components.
Professional Applications & Engineering Value
This M2 set screw is engineered to solve critical fastening challenges in precision assemblies. The alloy steel material, hardened to Rockwell C45, provides the necessary strength to prevent stripping and withstand dynamic loads. The cup point concentrates pressure on a small area, creating a superior bite that resists loosening from vibration—a common failure point in machinery and electronics. Its headless and compact metric design is indispensable for securing collars, gears, and pulleys on shafts where space is limited and a smooth exterior is mandatory. The right-hand coarse thread ensures quick and deep engagement, making it a reliable set screw for high-volume manufacturing and maintenance tasks.
Specification Summary & Compliance
This set screw conforms to the dimensional and tolerance requirements of DIN 916 / ISO 4029. The metric thread has a size of M2 x 0.4 mm with a Class 5g6g thread fit, ensuring precise manufacturing standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for use in various industrial and consumer products.
