• High-strength durability from Alloy Steel with a Rockwell C45 hardness, ensuring long-term performance in demanding applications.
• Precise and reliable fit with a Class 6g thread tolerance, guaranteeing consistent installation and secure fastening.
• Optimized for high-torque assembly featuring a headless, hex drive design that allows for flush mounting and easy installation in confined spaces.
• Robust coarse threading (M20x2.5mm) enables faster installation and provides excellent grip in a wide range of materials.
• Full regulatory compliance with RoHS 3 and REACH, making it safe for use in various industrial and international markets.
• Manufactured to international standards (DIN 915 / ISO 4028), ensuring interchangeability, quality, and reliability in global engineering projects.

Professional Applications & Engineering Value

This M20 alloy steel set screw is engineered to solve critical challenges in heavy-duty mechanical assemblies. Its headless design with a hex drive is ideal for applications where a protruding head is not feasible, allowing for a smooth, finished surface. The extended tip increases the contact area, providing superior resistance to rotational forces and vibration, a common failure point in machinery and automotive components. Manufactured from alloy steel and heat-treated to a Rockwell C45 hardness, it withstands high shear and tensile stresses. The Class 6g metric coarse thread (M20x2.5) ensures a secure and precise fit, reducing the risk of cross-threading and streamlining the assembly process in pulleys, gears, and coupling applications. This combination of design and material delivers reliable, long-term performance for demanding industrial fastening needs.
