Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M24 hex head screws deliver superior performance in construction, machinery assembly, and heavy equipment manufacturing. The Class 8.8 steel construction combined with Rockwell C21 hardness provides excellent resistance to shear and tensile stresses, preventing fastener failure in high-vibration environments. The coarse metric thread with 3mm pitch ensures rapid installation and reduced cross-threading risks, while the zinc plating offers reliable corrosion protection, making these screws ideal for outdoor and exposed applications. Fully threaded for maximum holding power, they are the go-to choice for structural connections requiring high tensile strength and long-term reliability.
Specification Summary & Compliance
This M24 x 3mm hex head screw features Class 6h thread fit per metric standards, ensuring precise dimensional accuracy. Manufactured in compliance with ISO 4017 (equivalent to DIN 933) specifications for hex head bolts, it meets rigorous industrial requirements. The product is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, adhering to environmental and safety regulations for hazardous substances. With a length of 70mm and fully threaded right-hand design, it provides consistent performance across applications requiring metric coarse threading and external hex drive compatibility.
