For securing and holding any type of round material to a flat surface round U bolts are an ideal option. This can include small diameter copper, iron or PVC pipes for internal plumbing, irrigation systems or for holding electric conduit or tubing.
These types of bolts are also used for affixing pipes and poles to exterior structures, to securing wood doweling or even for work with installing antennas or other types of round materials to the exterior of any building or structure.
Measurements and Terminology
All round U bolts have a true round interior of the top or the U component of the bolt. This allows the round pipe or tube to be held securely in place with contact over a larger area of the pipe or tube.
This, in turn, allows the pressure of holding the pipe or tube in place to be distributed over a greater area, helping to reduce the risk of over tightening slightly and cracking or bending the pipe or tube. Getting the right size of U bolt will be important in preventing this issue and also ensuring a secure fit with the pipe or tube.
The diameter or the U bolt is the actual diameter of each of the shanks. This will be the same for both legs of the bolt. The length is measured from the highest point of the U to the very end of the shank. Remember, this length needs to include enough length for the attachment of the nuts so it can be effectively secured.
The width is the measurement at the widest part of the bolt, typically at the top of the threads. This is measured from the inside, not on the outside of the bolt. This is important as it allows for easy selection based on the exterior diameter of the pipe or tubing you are using.
Tight Fit
In any application, it is essential to choose the right size of round U bolts based on what it will be used to hold. Avoid using U bolts that are oversized as they can lead to problems within the system.
U bolts that don’t fit tight to the pipe or tube can lead to vibration or rattling, particularly with plumbing or water lines. Even with poles, antennas and other objects, preventing the item from rubbing against the U bolt will prevent problems with surface damage or even failure of the component over time.
