Introduction
This manual provides essential instructions for the proper installation, use, and maintenance of your Hampton U-Bolt. Please read this guide thoroughly before installation to ensure safe and effective application.
Product Overview

Figure 1: Hampton U-Bolt assembly.
A close-up view of the Hampton U-Bolt, featuring its U-shaped zinc-plated metal body, threaded legs, a flat washer, and two hexagonal nuts securely fastened at the bottom. This image illustrates the complete U-bolt component.
The Hampton U-Bolt (Model 5230214, Ref.No. 222-208) is a versatile fastener designed for securing pipes, conduits, or other round objects to a support structure. Constructed from zinc-plated steel, it offers durability and corrosion resistance for various applications.
Key Features:
- Material: Zinc-plated steel for enhanced durability and corrosion resistance.
- Thread Diameter: 3/8 inch.
- Wire Diameter: 0.327 inch.
- Inner Diameter (between legs): 2-1/2 inches.
- Inside Length: 3-5/8 inches.
- Fastener Type: U-Bolt, U-shape head style.
Setup and Installation
Proper installation is crucial for the U-bolt's performance and safety. Ensure all components are present and undamaged before proceeding.
Required Tools (Not Included):
- Wrench (appropriate size for 3/8 inch nuts)
- Measuring tape
- Marking tool
Installation Steps:
- Prepare the Mounting Surface: Identify the location where the U-bolt will be installed. Ensure the surface is clean, stable, and capable of supporting the intended load.
- Position the Object: Place the pipe, conduit, or object to be secured within the U-bend of the U-bolt.
- Insert Legs Through Support: Guide the threaded legs of the U-bolt through pre-drilled holes in the support structure or mounting plate. The spacing of the holes should match the inner diameter of the U-bolt legs (2-1/2 inches center-to-center).
- Attach Washer and Nuts: Once the legs pass through the support, place the flat washer over both threaded ends. Then, thread a hexagonal nut onto each leg.
- Tighten Securely: Using a wrench, gradually tighten both nuts evenly. Alternate tightening each nut to ensure uniform pressure and prevent bending of the U-bolt or damage to the secured object. Do not overtighten, as this can strip threads or deform the U-bolt. Tighten until the object is firmly secured without crushing it.
- Verify Stability: After tightening, check that the secured object is stable and does not move excessively.
Operating Considerations
The Hampton U-Bolt is a static fastening component. Its "operation" involves maintaining a secure hold on the object it fastens. Ensure the U-bolt is used within its intended load-bearing capacity and environmental conditions.
- Do not exceed the recommended load for the U-bolt and the supporting structure.
- Avoid exposing the U-bolt to corrosive chemicals that may compromise the zinc plating, unless specifically designed for such environments.
- Regularly inspect the U-bolt for signs of wear, corrosion, or loosening.
Maintenance
Minimal maintenance is required for the Hampton U-Bolt. Periodic inspection is recommended to ensure continued performance and safety.
- Visual Inspection: Periodically check the U-bolt for any visible signs of damage, such as bending, cracks, or significant corrosion.
- Tightness Check: Re-check the tightness of the nuts annually, or more frequently in high-vibration environments. Retighten if any loosening is detected.
- Cleaning: If necessary, clean the U-bolt with a damp cloth to remove dirt or debris. Avoid abrasive cleaners that could damage the zinc plating.
- Replacement: If the U-bolt shows signs of severe corrosion, deformation, or thread damage, replace it immediately with a new, equivalent fastener.
Troubleshooting
Most issues related to U-bolts stem from improper installation or environmental factors. Here are common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Object is loose after installation | Nuts not tightened sufficiently; U-bolt size incorrect for object. | Retighten nuts evenly. Ensure U-bolt inner diameter matches object diameter. |
| U-bolt appears bent or deformed | Overtightening; excessive load; incorrect installation. | Replace the U-bolt. Review installation steps and load limits. |
| Corrosion or rust visible | Exposure to harsh environmental conditions; damage to zinc plating. | Clean and inspect. If severe, replace the U-bolt. Consider protective coatings for harsh environments. |
| Threads are stripped | Overtightening; cross-threading during installation. | Replace the U-bolt and nuts. Ensure proper alignment when threading. |
