Professional Applications & Engineering Value
This M24 hex head screw is engineered to address critical challenges in industrial settings, such as vibration resistance and long-term reliability. Made from high-quality steel with a zinc plated finish, it combats corrosion in outdoor or humid conditions, ideal for construction, machinery, and automotive assemblies. The metric coarse thread with a 3mm pitch ensures quick installation and robust holding power, while the Class 8.8 strength and Rockwell C21 hardness prevent deformation under high stress. Fully threaded and featuring an external hex drive, it simplifies maintenance and provides uniform load distribution, making it a top choice for heavy-duty fastening where precision and durability are paramount.
Specification Summary & Compliance
This fastener adheres to precise dimensional standards, including Class 6h thread fit for metric threads and compliance with ISO 4017 (equivalent to DIN 933). It meets regulatory requirements such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and material restrictions are upheld for industrial use.
