Hot-Dip Galvanized Hook Bolts

Hot-dip galvanized hook bolts are fasteners with a hook shape at one end and a threaded end. They are primarily used for connecting curtain wall joists, fixing roof purlins, hoisting precast wall panels, and pipe hanger systems. The hook end of these hot-dip galvanized hook bolts can be quickly hooked onto the edges of structural openings, channel steel, or embedded parts, forming temporary or permanent connections without the need for nuts, greatly improving installation efficiency. In building curtain wall projects, hot-dip galvanized hook bolts are commonly used to connect vertical joists to the main structure, bearing wind loads and their own weight. In factory roof systems, hot-dip galvanized hook bolts are used to fix purlins to roof beams. Since curtain walls and roof systems are constantly exposed to rain, ultraviolet radiation, and temperature fluctuations, hot-dip galvanized hook bolts provide an economical and efficient corrosion protection solution.

Product Feature

Quick Installation Structure: The hook can be inserted into openings or profile edges without tools, allowing for single-person positioning and increasing construction efficiency by over 50% compared to ordinary bolts.

Clear Load Transfer: The large contact area between the hook and the hole wall ensures uniform stress distribution and stable tensile and shear resistance. The inner side of the hook is typically machined into a flat or rounded surface, preventing damage to structural edges.

Full Hot-Dip Galvanizing Coverage: A uniform zinc layer is applied to the inner and outer surfaces of the hook's curved sections, threads, and shank, eliminating coating dead spots. The sharp corners at the hook's tip are blunted or rounded to prevent coating cracking.
