Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M24 hex head screws combine Class 8.8 steel construction with zinc plating to combat corrosion while maintaining structural integrity. The coarse metric thread (3mm pitch) ensures rapid assembly in construction frameworks, heavy machinery, and transportation equipment, where vibration resistance is critical. With partial threading and 150mm length, they provide optimal grip length for thick-section materials, preventing joint loosening under dynamic loads. These ISO 4014/DIN 931 compliant fasteners are ideal for applications requiring consistent clamping force and long-term reliability in manufacturing plants, infrastructure projects, and equipment maintenance.

Specification Summary & Compliance

This M24 x 3mm hex head screw features Class 6h thread fit tolerance and 54mm minimum thread length, manufactured to ISO 4014, DIN 931, and SAE J1199 specifications. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety and regulatory adherence for global industrial supply chains.
