Umbrella Handle Anchor Bolt

The umbrella-shaped 180° curved hook section penetrates deep into the concrete foundation, providing an uplift resistance far exceeding that of standard U-shaped anchor bolts and effectively preventing the bolt from being pulled out of the concrete. It is suitable for high-tension and high-vibration applications, ensuring no loosening or detachment even after long-term use.

The umbrella-head anchor bolts are manufactured using high-quality steel through an integral hot-bending process, eliminating welded joints and ensuring stable mechanical properties. This effectively prevents material embrittlement and strength reduction caused by welding, resulting in excellent overall compressive and fatigue resistance that meets stringent engineering standards.

The hook design effectively prevents the bolt from floating or shifting during concrete pouring, ensuring precise positioning and secure fixation during embedding. No complex installation procedures are required; the bolts are compatible with automated assembly and on-site embedding operations, significantly reducing construction difficulty and improving project efficiency.

A full range of sizes from M12 to M48 is available, with diameters and lengths customizable to precise engineering specifications. The bolts are suitable for foundation projects with varying load-bearing capacities, meeting diverse anchoring needs ranging from small equipment to large, tall structures.

This bolt is available with various surface treatments, including natural finish, blackening, electrogalvanized, and hot-dip galvanized. The hot-dip galvanized version features a zinc coating thickness of ≥80μm, offering salt spray resistance and corrosion protection. It is ideally suited for harsh environments such as outdoor open-air settings, humid workshops, and coastal areas with high salt spray, thereby extending the service life of the anchorage.
