Key Features & Benefits at a Glance

  • Superior corrosion resistance with black-oxide coating on alloy steel, extending service life in harsh industrial environments.
  • Enhanced gripping power and component protection from the precision brass tip, preventing damage to mating surfaces.
  • High-strength performance with a Rockwell C28 hardness rating, ensuring reliable, long-term fastening under load.
  • Secure and efficient installation using the 4 mm hex drive, allowing for high torque application in confined, headless designs.
  • Precise and reliable thread engagement with Class 5g6g metric coarse thread (M8 x 1.25 mm), reducing the risk of cross-threading.
  • Broad industrial compatibility due to compliance with ASME B18.3.6M, ensuring interchangeability and meeting engineering specifications.
  • Safe for regulated applications as it is RoHS 3 and REACH compliant, adhering to strict environmental and health standards.

Professional Applications & Engineering Value

This M8 set screw is engineered to solve critical fastening challenges in demanding industrial settings. The black-oxide alloy steel construction provides excellent resistance to rust and wear, making it ideal for machinery, automotive assemblies, and production equipment exposed to oils and moisture. The brass tip is crucial for applications requiring repeated adjustments, as it marries high clamping force with softness to prevent galling and damage to costly shafts or collars. Combined with a coarse thread and Class 5g6g thread fit, it ensures quick assembly and a secure hold in softer materials or where vibration resistance is paramount. The headless, hex drive design is perfect for space-constrained applications, providing a flush finish and reliable torque transfer.

Specification Summary & Compliance

This set screw features an M8 x 1.25 mm coarse thread with a Class 5g6g thread fit, ensuring dimensional accuracy per metric standards. It is manufactured to meet the ASME B18.3.6M specification. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
