- Efficient installation and removal with a 10mm hex drive, providing a secure tool grip and reducing assembly time.
- Wide compatibility and reliable fit with Class 5g6g coarse threads, facilitating easy engagement and consistent performance.
- Guaranteed quality and consistency through compliance with DIN 916 and ISO 4029 international standards.
- Safe for use in regulated environments as it is fully compliant with RoHS 3 and REACH environmental directives.
Professional Applications & Engineering Value
This M20x2.5x100mm alloy steel set screw is engineered to solve critical challenges in industrial assembly and machinery. Its headless design and hex drive allow for flush mounting in confined spaces, while the cup point ensures a firm, non-slip grip on shafts and collars, preventing axial movement under high torque and vibration. Manufactured from hardened alloy steel with a Rockwell C45 rating, it withstands severe mechanical stress, making it ideal for securing gears, pulleys, and other rotating components in automotive, manufacturing, and heavy equipment. The coarse thread and Class 5g6g fit provide quick, reliable fastening, reducing the risk of cross-threading and ensuring consistent performance in high-volume production lines.
Specification Summary & Compliance
This set screw adheres to precise dimensional and performance standards, including a metric M20x2.5 coarse thread with a Class 5g6g thread fit for consistent engagement and tolerance. It is manufactured in compliance with DIN 916 / ISO 4029 specifications, ensuring interchangeability and reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in environmentally sensitive applications.
