S-SEN U-bolts (commonly known as "riding bolts") are fasteners with a simple structure and reliable performance. Their core design consists of a U-shaped body with threaded ends. The thread tolerance is strictly controlled to the 6g level. Tightening with nuts at both ends securely clamps tubular or flat objects. The product range covers three material series, combined with diverse surface treatments and multiple structural forms, adapting to the demanding requirements of various fields such as automotive and construction. S-SEN is a trustworthy provider of U-bolt solutions.
The core of the S-SEN U-bolt is the U-shaped body and the threaded sections at both ends. It is named "riding bolt" because its fixing method resembles a rider on a horse. The thread tolerance is uniformly 6g, ensuring precise matching with the nuts. When tightened, it forms a uniform clamping force, securely fixing various tubular and flat workpieces, adapting to multiple installation scenarios.

2. Refined Surface Treatment
To improve corrosion resistance and service life, S-SEN provides three levels of surface treatment processes, which can be selected according to the environmental corrosion intensity:
- Basic treatment: Blackening, white zinc plating, salt spray test ≥72 hours, suitable for conventional dry environments;
- Enhanced treatment: Hot-dip galvanizing (zinc layer ≥85μm), Dacromet coating, salt spray resistance exceeding 1000 hours, suitable for humid and moderately corrosive environments;
- Special treatment: Reinforced hot-dip galvanizing, specially designed for highly corrosive environments, resisting acid, alkali, and salt spray corrosion.
3. Multi-form Structural Classification
S-SEN U-bolts are classified by shape, covering general and special scenarios, offering strong adaptability:
- Semi-circular: General-purpose model, suitable for DN15-DN300 pipe diameters, widely used for pipe fixing;
- Square right-angle: Suitable for steel structure fixing (such as C-channel steel brackets), providing stable and secure clamping;
- Triangular/Rhombus: Customized models, used for connecting special mechanical components, ensuring reliability in complex working conditions.
1. Automotive Industry: Securing leaf springs and chassis components, with a load capacity of ≥5 tons, suitable for demanding vibration conditions;
2. Piping Systems: Fixing water supply, drainage, and HVAC pipes, requiring matching according to pipe diameter D0 parameters to ensure no displacement;
3. Construction Engineering: Connecting steel structure beams and columns, and fixing curtain wall frames, providing stable support;
4. Rail Transit: Used for railway bridge supports and overhead line fixation, meeting high strength and high weather resistance requirements.
