china Fastenal u bolts factory


Fastenal U-bolts, representing non-standard fasteners, are named for their unique "U"-shaped structure and are also known as saddle bolts in the industrial field. Fastenal U-bolts feature threaded ends for quick tightening with nuts. Their curved sections can be customized into semi-circular, square, right-angled, or triangular shapes to precisely fit different pipe diameters or sheet metal requirements. This design allows them to securely wrap around the fixed object like "riding a horse," combining flexibility and reliability.

Material System and Performance Advantages

Carbon Steel Series: Primarily based on Q235A and Q345B, galvanized for excellent corrosion resistance, suitable for general environments such as building installation and ordinary mechanical parts connections, offering outstanding cost-effectiveness.

Stainless Steel Matrix: Covering various grades including 304, 316L, and 310S, 316L material, due to the addition of molybdenum, exhibits excellent resistance to chloride ion corrosion, making it suitable for extreme conditions such as marine engineering and chemical pipelines. 310S, with its high-temperature resistance (up to 1150℃), is the preferred choice for mounting high-temperature equipment.

Alloy Steel Reinforced Version: Fastenal U bolts undergo heat treatment to enhance strength, achieving a tensile strength exceeding 800MPa. Suitable for high-load applications such as leaf spring connections in trucks and bridge/tunnel supports, ensuring stability under long-term vibration.

Cross-Industry Application Map

Automotive Industry: As a key connector in the chassis system, it secures leaf springs to the frame, withstands dynamic impact loads during vehicle operation, and ensures suspension system stability.

Energy Infrastructure: In oil and gas pipeline projects, it is used with pipe clamps to create rigid constraints, preventing displacement due to thermal expansion and contraction or fluid impact, while also reducing fatigue damage to welds caused by vibration.

Power Facilities: As a core component of non-standard power fittings, it is used for fixing crossarms on utility poles and assembling cable clamps. Its corrosion resistance can withstand outdoor sun and rain, extending the service life of power grid facilities.

Building Construction: Fastenal U bolts play an anchoring role in cantilever scaffolding embedded parts and steel structure purlin connections, ensuring tightness of node connections through precise thread accuracy (compliant with JB/ZQ4321-2006 standard).
