Focus on U-bolts
Feb 05,2026
U-bolts are core fasteners in the power industry.
Suspension clamp fastening: XGU/CGU suspension clamps, secured with U-bolts, are used to clamp steel-cored aluminum stranded conductors of medium and small cross-sections. In conjunction with saddle plates and insulator strings, these clamps bear the weight of the conductor as well as wind-induced lateral loads. They are suitable for 10kV–220kV transmission lines and require the application of aluminum wrapping tape to prevent damage to the conductor.

Basic Definition and Structure of U-Shape Screws
Shape: Made by bending round steel into a U-shape, with fully threaded ends. Used in conjunction with matching nuts and saddle plates/pressure plates; the U-shaped section wraps around the pipe or cylindrical component, while the saddle plate presses down on top. Tightening the nut secures the assembly—a fastening method commonly referred to as “riding a horse.”

Structural advantages of U-bolts
The open design of the U-shaped screw allows it to be directly slipped over the object to be secured (such as pipes, brackets, or mechanical components) without the need for pre-drilling holes or removing other components, significantly improving installation efficiency.

Selection and Installation Recommendations for U-Bolts
Material Selection: In humid environments, prefer stainless steel or galvanized U-shaped screws; in dry environments, carbon steel bolts can be used to reduce costs. Specification Matching: Select bolt diameters (such as M12, M16) based on load-bearing requirements to avoid overloading and subsequent fracture.

The adaptation advantages of U-shaped screws
Rust-resistant and corrosion-resistant: Since agricultural machinery is often exposed to humid and muddy environments for extended periods, U-bolts are frequently made from stainless steel or galvanized materials, effectively prolonging their service life.

The core application scenarios of U-bolts in agricultural machinery
The depth-limiting wheel is used to control the tillage depth. Its components—including the wheel rim, wheel hub connector, and inner sleeve—are secured to the longitudinal beams of the plow frame by U-shaped screws. The open design of the U-shaped screws allows for quick adjustment of the depth-limiting wheel’s height, making it adaptable to the cultivation needs of different crops.

Maintenance and Replacement of Automotive U-Bolts
During routine car maintenance, it’s necessary to check the tightness of the U-bolts to ensure they are neither loose nor damaged.

Key considerations for automotive U-bolts
Material Influence on Torque: U-bolts made of stainless steel have lower strength than those made of alloy steel of the same specification. Therefore, the tightening torque should be reduced by 10% to 15% to prevent thread stripping or breakage.

The primary uses of automotive U-bolts
Body structure: Used to secure the body frame, support beams, crossmembers, and other components, helping to maintain the vehicle’s stability and structural integrity.
