how to measure U bolts

In construction and engineering, there are many essential fasteners that ensure the stability and strength of structures. One widely used tool is the U-bolt. As the name suggests, these fasteners are shaped like a “U” and are critical in securing beams, columns, or other structural members to concrete surfaces.

 

Due to their importance, it is vital to understand how to measure U-bolts and what the most common measurements are within the construction industry. In addition, it is essential  to consider certain criteria when selecting appropriate U-bolts for a specific application, as well as industry standards and codes related to their use.

 

How to measure U bolts?

The following are the methods used to measure U-bolts, along with some of the most common measurements:


  • Thread length: is the dimension of the bolt around the bend, excluding the outside.

  • Inside height: this is measured from the bottom to the top of the curve. The leg length may vary depending on the application.

  • Inside diameter: this is the distance between the two legs of the bolt. This measurement is critical to ensure that the U-bolt fits appropriately around the fastened object.

  • Thread Size: this measurement refers to the thickness of the bolt material.
  •  

    Here are some examples of U-bolt measurements:

    Please note that these measurements are examples only and may vary depending on the manufacturer and application. When selecting U-bolts, it is essential  to consult the project specifications to ensure the proper dimensions are selected for effective and safe fastening.

    Common Materials Used in the Manufacture of U-Bolts

    Various  materials are used to manufacture  U-bolts, each with its  characteristics and suitability for specific applications. Here are a few common materials:
    • Carbon steel: provides good tensile strength and durability, making it suitable for general construction and industrial applications.


    • Stainless Steel: highly resistant to corrosion and oxidation, making it ideal for marine, outdoor, or moisture-exposed environments.


    • Steel Alloys: used when greater strength and toughness are required. These alloys may include grade 8 or 10 alloy steel, typically used in applications requiring extreme strength.


      When selecting a material, it is critical to consider corrosion resistance, mechanical strength, and the necessary durability properties to ensure integrity and safety.

       

      Relevant Standards for U-Bolt Use

      It is indispensable to adhere to established standards set by recognized organizations to ensure U-bolts' quality, safety, and reliability. Some standards used in the United States are:

       

      • ANSI/AISC 360: This code establishes design and construction requirements for steel structures, including bridges and buildings.


      • AWS D1.1: Used for welding specifications in steel structures, this standard provides guidelines for designing and fabricating welded connections, including using U-bolts as fasteners.


      In addition to these guidelines, specific regulations and codes at the state or local level may be considered when using U-bolts in structural contexts.
