U Type Clevis Plate

U Type Clevis Plate

U and UJ series U bolts are preferred connecting components for suspension strings on tangent towers, and they are also used for overhead ground wire suspension points. The threaded end fastens directly to the tower cross arm, simplifying the cross arm structure, while the looped end connects to the insulator string, allowing a flexible pivot point. The assembly carries vertical loads and permits the insulator string to swing freely, making these bolts essential for tangent tower applications in overhead transmission and distribution lines.

Description

 Material & Design

 

These U‑bolts are manufactured from high‑quality steel, with all parts hot‑dip galvanized except the stainless steel split pin. The galvanized layer is uniform and dense, providing excellent corrosion resistance for coastal and industrial environments. The U‑series bolts feature a threaded shank that bears tensile loads; the UJ‑series adds a shoulder (or step) below the thread, which counteracts bending moments from horizontal loads, improving mechanical performance. Common models include U‑1670, U‑1680, U‑1870, U‑1880, U‑2080, U‑2280, and UJ‑1880, UJ‑2080. All products conform to national power industry standards.

 

 Quality Control

 

Thread accuracy is critical for smooth assembly with cross‑arm nuts. We use a rolling process to produce clean, full‑form threads with consistent fit. For UJ types, the shoulder is forged integrally with the shank, and its concentricity is checked with dedicated gauges. Every piece undergoes thread gauge inspection and galvanized layer thickness measurement before packing. Our factory is ISO‑certified and recognised as a high‑tech enterprise, with full traceability from raw material to finished bolt.

 

 Customization & Ordering

 

We support OEM/ODM to adjust thread sizes, shank lengths, or shoulder designs according to your cross‑arm specifications. Standard models are kept in stock for 7‑working‑day delivery. Custom orders take about 2 weeks after sample approval. We accept mixed‑model orders within the same batch. Monthly production capacity exceeds 800,000 pieces, ensuring reliable supply for large projects.

 

 Packaging & After Sales

 

Threads are protected with plastic caps during transport to avoid damage. Export packing includes anti‑rust film and cartons. We offer EXW, FOB, and DDP terms, multiple currency payments, and a one‑year global warranty. Our after‑sales team responds to any quality issues within 24 hours.
