Quick Specs
What Buyers Should Know Before Sourcing Carbon Steel U Bolts
Export orders need complete dimensions
Carbon steel U bolts are shaped fasteners, so an export quotation needs more than diameter and overall length. Buyers should confirm inside width, bend radius, leg length, thread length, thread pitch, end style, nut requirement and finish. For pipe clamp applications, the pipe outside diameter and saddle plate requirement should also be checked. XZ Fastener’s U bolt dimensions guide helps buyers define diameter, width, length and thread length before ordering.
Match bend shape with the assembly
Round bend U bolts are often used for pipe and tube clamping, while square U bolts are common for trailer axles, frames and brackets. Bend symmetry, leg parallelism and thread fit should be checked before shipment, especially when U bolts must match existing plates or clamps. Buyers can review the U shape bolt product reference when preparing a drawing or sample-based inquiry.
Common Purchasing Descriptions
Clear purchasing descriptions help XZ Fastener confirm material, bending, threading, coating, matching parts and export packing. Common inquiry formats include:
- DIN 3570 carbon steel U bolts, M10, zinc plated, supplied with two hex nuts.
- Round bend pipe clamp U bolts, carbon steel, black oxide, custom inside width.
- Square bend U bolts for trailer axle, grade 8.8, hot dip galvanized, with nuts and washers.

Detailed Specifications Table
| Предмет | Available Specification | Export Buyer Notes |
|---|---|---|
| Product type | Round U bolts, square U bolts, semi-round U bolts and drawing-based U bolts | Send a drawing or sample photo when bend shape is not standard. |
| Стандарт | DIN 3570, pipe clamp U bolts, trailer U bolts or customer drawing | Standard selection affects bend radius, thread length and matching hardware. |
| Diameter range | Common metric sizes such as M6 to M30; inch sizes available upon request | Diameter should be matched with clamp load and nut grade. |
| Inside width | According to pipe diameter, axle size, bracket width or drawing requirement | Measure inside width clearly; do not provide only outside width. |
| Leg length | Short, standard or extended legs according to assembly thickness | Include usable thread length and non-thread shank length if required. |
| Thread type | Metric coarse, metric fine, UNC, UNF or special pitch | Provide pitch when matching existing nuts, clamps or assembled hardware. |
| Материал | Low carbon steel, medium carbon steel or alloy steel | Material is selected according to load, bending process and strength requirement. |
| Strength | 4.8, 5.8, 8.8 or custom mechanical requirement | Higher strength may require controlled material and heat treatment review. |
| Finish | Plain, zinc plated, yellow zinc, black oxide, phosphate, HDG, Dacromet, Geomet | Coating should match corrosion exposure, nut fit and transport conditions. |
| Packing | Bulk cartons, bag sets, small boxes, wooden cases or pallet packing | Nut and washer sets can be packed together when specified. |
Material and Grade Explanation
Carbon steel U bolts are commonly chosen for pipe supports, vehicle brackets, equipment frames and structural clamps because they provide practical strength and flexible forming. Low carbon steel is often used for general-duty clamp applications, while medium carbon steel or alloy steel may be selected when higher tensile strength or tighter mechanical performance is required.
Grade selection should be reviewed with the bend radius, thread length, nut grade, coating and tightening method. Higher strength is not always a direct replacement if the bend area, mating plate or installed torque is not suitable. Buyers comparing mechanical grades can review XZ Fastener’s guide on what 8.8 means on a bolt before final specification.
Surface Finish Selection Guide
| Finish | Typical Use | Export Purchasing Consideration |
|---|---|---|
| Plain or oiled | Indoor machinery, temporary protection or further processing | Lower corrosion resistance; moisture control is important during shipment. |
| Zinc plated | General pipe clamps, equipment brackets and indoor construction use | Common for standard carbon steel U bolts needing basic protection. |
| Yellow zinc plated | Visible clamp hardware, replacement stock and general assembly | Confirm color requirement and local environmental rules before ordering. |
| Чернение | Indoor machinery, black hardware sets and lower-reflection assemblies | Usually requires oil protection and is not preferred for outdoor exposure. |
| Hot dip galvanized | Outdoor pipe supports, guardrails, utility frames and exposed steelwork | Thread fit and matching nut allowance should be confirmed before production. |
| Dacromet or Geomet | Higher corrosion resistance with controlled coating thickness | Available upon request for project specifications and special assemblies. |

Manufacturing and Quality Control
Carbon steel U bolts are usually produced through wire or bar cutting, end threading, bending, heat treatment when required, surface finishing, inspection and packing. Depending on diameter and order quantity, threading may be completed before or after bending. For export orders, bending tooling, bend radius, leg parallelism, thread position and packing method should be confirmed before bulk production.
Inspection may include diameter checking, inside width, leg length, thread length, thread gauge, bend symmetry, surface appearance, hardness, coating thickness and carton verification. The guide on cutting, bending, threading and coating gives buyers useful context for formed fasteners that require controlled shape and thread quality.
Приложения
Carbon steel U bolts are used where a fastener must clamp around a round, square or irregular component while providing threaded legs for tightening. Common export applications include:
- Pipe clamps, conduit supports, water pipe fixing and industrial piping brackets.
- Trailer axles, vehicle suspension clamps, agricultural machinery and equipment frames.
- Guardrail assemblies, steel structures, mounting plates and base brackets.
- HVAC supports, cable tray frames, solar mounting support and construction hardware.
- OEM assemblies requiring custom inside width, leg length, thread length and export packing.
