Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M8 set screws deliver exceptional performance in machinery, automotive assemblies, and marine equipment where corrosion resistance is critical. The 316 stainless steel material provides superior protection against chlorides and acidic environments, while the coarse thread pitch (1.25mm) ensures rapid installation and reduced cross-threading risks. The headless design with hex drive offers space-saving advantages in confined assemblies, and the cup point tip creates permanent seating for shaft collars, gears, and pulleys—preventing slippage under vibration and heavy loads. These metric set screws are specifically designed to maintain clamping force in high-stress applications where reliability cannot be compromised.
Specification Summary & Compliance
This M8 x 1.25mm x 20mm set screw features Class 6g thread tolerance per ISO metric standards, ensuring precise dimensional accuracy. Manufacturing conforms to DIN 916/ISO 4029 specifications for dimensional and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances above threshold limits. Right-hand coarse threading provides optimal engagement in most industrial applications.
