Key Features & Benefits at a Glance
- Superior torque transmission enabled by the square head and external square drive, preventing tool slippage during high-tension installations.
- Exceptional durability and wear resistance thanks to the high-strength alloy steel construction with a Rockwell C23 hardness rating.
- Reliable and fast installation with a coarse 2.5mm thread pitch, ideal for quick assembly in heavy-duty industrial settings.
- Precise and secure fastening ensured by the Class 6g thread fit, offering excellent dimensional accuracy for consistent performance.
- Enhanced grip and holding power from the extended 15mm tip diameter, providing a larger contact area for critical applications.
- Guaranteed material integrity and compliance with stringent industry standards, including DIN 479 for dimensional conformity.
- Safe for use in regulated environments as it is fully compliant with RoHS 3 and REACH environmental directives.
Professional Applications & Engineering Value
This M20 square head set screw is engineered to solve critical challenges in heavy machinery, automotive, and construction assemblies where vibration and high loads are common. The alloy steel material, combined with Rockwell C23 hardness, provides the necessary strength to resist deformation under extreme stress. The coarse metric thread with a 2.5mm pitch ensures rapid installation and reduces the risk of cross-threading, while the extended tip offers superior bite into components, preventing loosening. Its external square drive design allows for high-torque application, making it an ideal heavy-duty fastener for permanent or semi-permanent settings where reliability is non-negotiable.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 6g thread fit for metric coarse threads (M20x2.5) as per DIN 479. The extended tip features a diameter of 15 mm with a tolerance of -0.27mm to 0 and a length of 5.3 mm with a tolerance of -0.3mm to 0, ensuring consistent performance. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming its environmental safety and suitability for global industrial markets.
