Professional Applications & Engineering Value
This M6 hex set screw is engineered to address critical alignment and security challenges in industrial machinery, automotive assemblies, and precision equipment. The Class 8.8 steel material and Rockwell C20 hardness provide exceptional shear and tensile strength, preventing failure under vibration and dynamic loads. The extended tip with controlled diameter and length tolerances ensures positive seating in shallow or pre-drilled holes, minimizing component slippage in shaft-hub connections and adjustable mechanisms. Compliant with DIN 561B, it guarantees dimensional consistency for maintenance and OEM applications, while the external hex drive facilitates efficient installation with standard tools, reducing assembly time and improving workflow reliability.
Specification Summary & Compliance
This set screw features M6 x 1mm coarse threads with Class 6g thread fit per ISO metric standards, ensuring precise tolerance control. Manufacturing adheres to DIN 561B specifications for dimensional accuracy, including head width (8 mm), length (25 mm), and tip dimensions. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted substances for safe use in global industrial markets.
