Professional Applications & Engineering Value
This M12 metric set screw is engineered to address critical fastening challenges in heavy machinery, automotive assemblies, and construction equipment. Its Class 8.8 steel construction and Rockwell C20 hardness provide exceptional resistance to shear and tensile forces, preventing failure under dynamic loads. The coarse thread with Class 6g fit ensures quick assembly and reliable grip in materials where fine threads might strip, while the extended tip enhances alignment and secures components against shifting. Ideal for industrial applications requiring repeatable, high-strength fastening, this screw minimizes downtime and maintenance costs through its robust external hex drive and compliance with international standards.
Specification Summary & Compliance
This set screw maintains precise Class 6g thread fit per ISO metric standards, with a 120mm length, M12 thread size, and 1.75mm pitch. Manufacturing adheres to DIN 561B specifications, ensuring dimensional consistency. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for safe use in regulated industries.
