U-bolts are fasteners shaped like the letter "U", mainly used to fasten cylindrical or elongated components such as pipes and profiles. Through their threaded ends, they connect with nuts and clamp the workpiece to brackets or bases, providing stable fixation.
The structure of a U-bolt is based on the principle of a "clamping grip," which allows it to fit tightly against the contours of the workpiece and enhance fastening stability.
Main Structure
It consists of a bent "U-shaped rod" and "threaded sections" at both ends. The curvature of the arc section must match the outer diameter of the workpiece (e.g., a pipe) to ensure proper contact; the threaded sections have external threads for installing nuts and washers.
Key Structural Features
Some models are equipped with rubber gaskets or anti-slip grooves on the inner surface of the bent section. This prevents scratches on the surface during clamping and increases friction to stop components from slipping.
The length of the threaded section is calculated according to the thickness of the bracket to ensure sufficient thread engagement depth when the nut is tightened, preventing the nut from loosening.
The rod body is usually made from a single piece of steel, bent into the required shape. This eliminates the presence of weld seams, prevents damage under load, and ensures overall mechanical strength.
The selection of materials and surface treatment methods is primarily determined by the load requirements, corrosion degree, and operating temperature conditions.
