Key Features & Benefits at a Glance
- Superior holding power with Rockwell C45 hardness for maximum resistance to wear and loosening in high-vibration environments
- Precise Class 6g thread fit ensures reliable engagement and consistent clamping force for secure component positioning
- Extended 5.3mm tip provides deeper penetration and superior bite into shafts and hubs, preventing slippage
- Heavy-duty alloy steel construction delivers exceptional tensile strength and durability for demanding industrial applications
- Coarse M20x2.5mm thread allows for faster installation and higher resistance to cross-threading compared to fine-pitch alternatives
- Hex drive design enables high-torque installation with standard tools, ensuring a tight, flush fit in confined spaces
- Full regulatory compliance with DIN 915/ISO 4028, RoHS 3, and REACH guarantees material safety and international interchangeability
Professional Applications & Engineering Value
This M20 set screw is engineered to solve critical alignment and security challenges in industrial machinery, power transmission systems, and precision equipment. The alloy steel core, hardened to Rockwell C45, provides the necessary strength to withstand high rotational forces and shock loads without deforming. Its extended tip and coarse metric thread work in tandem to create a deep, secure locking action on shafts, collars, and gears, effectively preventing axial movement and maintaining positional accuracy. The hex headless and right-hand thread design is ideal for applications where a flush surface is required and standard right-hand tools are used, streamlining maintenance and assembly processes in heavy-duty environments.
Specification Summary & Compliance
This metric set screw features an M20x2.5mm coarse thread with a Class 6g tolerance for precision fit. The extended tip has a length of 5.3mm (-0.3mm to 0 tolerance) and a diameter of 15mm (-0.43mm to 0 tolerance). It is manufactured in accordance with DIN 915 / ISO 4028 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
