When it comes to supporting pipe work - and specifically pipes in which liquids and gasses pass through - there might be no greater tool than the U-bolt industrial fastener. Yes, the U-bolt - it's almost exactly like it sounds, a bolt in the shape of the letter U. It also features screw threads on both ends of the bolt to adequately secure the pipe work or other intended application.


While U-bolts may be most synonymous with supporting pipe work, they're also common in building and construction applications - like roofing and foundation stability - to even securing motor and engine shaft components. This is because of their strength and ability to be customized, as they can be made to serve the application.  U-bolts come in both standard and custom sizes, and are available in materials such as carbon steel, alloy steel, and stainless steel as well as with zinc, fluorocarbon, cadmium and hot dipped galvanized coatings. Some different types of U-bolts include rounded, long tangent, square and slant (vineyard/orchard).

Here's a closer look at some other details of U-bolts. Think of it as the "nuts and bolts" of the industrial fastener:

  • Their purpose: The main role of U-bolts is to provide a clamping force to hold two components together. 
  • Measurement: U-bolts are measured based on the screw thread length, inside diameter, inside height and thread size. U-bolts were originally measured using pipe work in engineering speak. Hence, a U-bolt would originally be characterized by the pipe's size that it was supporting.
  • Price: In general, standard commodity U-bolts are inexpensive. Custom pricing is typically dictated by quantity.
  • Convenience: Not only are U-bolts tough and effective - as they're available in a variety of different material and strength grades to provide adequate clamping force - but they're also very easy to administer and they're versatile enough that they can apply to various applications and industries. What's more is that there's zero material waste when it comes to using U-bolts. 
  • Definition: Five elements define the U-bolt: material type, rod diameter, inside diameter (between the legs), inside length and thread dimensions.
  • Finish: U-bolts can also come in specialized finishes to stand up better to the environments they're intended to function in. For instance, for a U-bolt that is going to be working in humid or corrosive environments, a corrosion-resistant material like type 316 stainless steel or carbon steel with a hot dipped galvanized finish should be on the docket. 

As you can see, U-bolts are an easy, convenient and affordable type of industrial fastener for joining two items together. While the early roots of U-bolts may have been rooted in securing pipe work, the uses of this handy device have since expanded to include construction, automotive and architectural applications, among others.
