Stainless Steel U-Bolts IN STOCK!

Lightning Bolt is an ISO 9001

U-bolts are a type of industrial fastener most commonly known for securing piping in which liquids and gases flow. Their main function is to provide a clamping force to hold together two components. The U-Bolt, by no surprise, is shaped in the letter “U” and is threaded on both ends. The unique shape of the U-bolt helps provide an added amount of stability when securing piping or other material.  The use of stainless u-bolts, such as 304 stainless steel u-bolts and 316 Stainless steel u-bolts are often used when corrosion resistance is important.  Other options include PTFE coated u-bolts as well as neoprene coated u-bolts.

Initially U-bolts were measured based on the size of the pipe that they were supporting – ex: a 2” U-bolt would support a 2” pipe. This is still a common way of identifying U-bolts, although a more precise measurement can be made by measuring the thread size, thread length, inside diameter, and inside height.


Although commonly thought of for securing pipes, the U-Bolt has proven to be very adaptable, and has various applications across a wide range of industries, including the automotive, construction and architectural industries. For example, they can be used as anchors for roofs and foundations, and support for frames, cables, and conduits. In the automotive industry, U-bolts are used for engine shaft component support. U-bolts have been proven to be a versatile industrial fastener. U-bolt plates, which are also kept in stock, are commonly used with U-bolts for further support.
