Professional Applications & Engineering Value
This heavy-duty hold-down bolt addresses critical engineering challenges in industrial fastening where vibration resistance and secure anchoring are paramount. The zinc-plated steel construction provides essential corrosion protection for machinery, equipment mounting, and structural applications exposed to harsh conditions. The 45° flat hook profile with 1/2" length creates a positive locking mechanism that prevents accidental disengagement, while the partially threaded UNC coarse design allows for precise adjustment and maintains clamping force despite dynamic loads. With 60,000 psi tensile strength and Rockwell B70 hardness, this fastener delivers reliable performance in material handling systems, transportation equipment, and industrial machinery where failure is not an option.
Specification Summary & Compliance
This hold-down bolt features precise Class 2A thread fit with 1/4"-20 UNC coarse threading and partial threading extending 2 3/4" along the 4 3/4" shaft. Manufactured to industry standards with right-hand thread direction and dimensional accuracy. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
