Professional Applications & Engineering Value
This M8 hex set screw delivers critical engineering value in industrial settings where component slippage can cause equipment failure. The Class 8.8 steel construction provides the tensile strength needed to withstand vibrational forces, while the extended tip with controlled diameter tolerance creates a deeper seating point in mating components. Its coarse metric thread (1.25mm pitch) enables rapid assembly in production environments, and the external hex drive accommodates high torque requirements without stripping. Manufactured to DIN 561B specifications, this fastener solves alignment and security challenges in machinery, automotive assemblies, and precision equipment where durable set screws are essential for long-term operational integrity.
Specification Summary & Compliance
This set screw maintains Class 6g thread fit tolerance per ISO metric standards, ensuring precise engagement. It conforms to DIN 561B manufacturing specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for restricted substance-controlled applications. The extended tip features a diameter tolerance of -0.18mm to 0 and length tolerance of 0 to 0.3mm for consistent performance.
