Professional Applications & Engineering Value
This M8 set screw is engineered for precision industrial applications where secure component positioning is critical. The black-oxide alloy steel construction offers superior corrosion resistance, while the Rockwell C28 hardness ensures the fastener maintains its integrity under repeated stress. The soft brass tip is specifically designed to prevent marring or damaging precision shafts, gears, and collars in machinery assembly, making it ideal for power transmission systems and precision equipment. The Class 5g6g thread fit provides excellent vibration resistance, reducing the risk of loosening in dynamic environments. With its headless design and 4mm hex drive, it's perfect for applications where space is limited and a flush finish is required.
Specification Summary & Compliance
This metric set screw features M8 x 1.25mm coarse threads with Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy. Manufactured to ASME B18.3.6M specifications with a length of 30mm and 4mm hex drive. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications.
