- Round U Bolts are the shape of a "U" with two legs. The threaded ends are designed for use with washers and nuts, and can also be used with a crosspiece spanning both threaded arms of the bolt, to make it more secure in certain settings and uses. U-bolts are designed to be inserted through holes that have already been drilled or punched
- Round bend U-bolts are typically used for attaching pipe or steel round bar to a round wood or steel post. Another common application is to secure or hang pipe in mechanical installations. Square bend U-bolts are typically used for attaching product to a square shaped post. They can also be embedded in concrete and used as anchor bolts
- Description Sizing: To help compare different U Bolts we have converted the Width (W), Length (L) and Thread (T) of our imperial range to "mm"
- Material / Coating: Zinc Plated is the most common fastener of plating due to its the low cost and shiny bright silver finish. A thin layer of Zinc is applied by either electroplating or mechanically. It is intended to be used internally. Whilst some people use it externally it isn’t recommended if corrosion is a concern. If you want a fastener that will withstand the outdoor elements choose from our Stainless steel or Galvanised range
- Is Zinc and Galvanise Interchangable: Due to plating thicknesses galvanised and zinc plated threads are not interchangeable. A zinc nut will not wind onto a galvanised u bolt without damaging the threads and a galvanised nut will be too loose on a zinc plated thread
- Galling: can occur when excessive pressure is used to tighten a nut onto a thread, common with stainless fasteners but can also be an issue with other materials. Fasteners with damaged or fine threads are particularly prone to galling.
Some suggestions to help prevent thread galling:
Tightening the nut more slowly without excessive pressure, will frequently reduce or sometimes solve completely, the problem. As the installation RPM speed increases, the heat generated with friction during tightening escalates the chances of thread galling.
Reduce the friction by applying a suitable lubricant to the thread frequently eliminates thread galling. Typical lubricants are chloride-paraffine, molykoat lacquer, molybdenum disulphide, high pressure oil, graphite, mica, or talc, some assemblies where there is extreme pressure, corrosion resistant grease or waxes may also be effective - What does TPI stand for?: TPI stands for “threads per inch” which literally means the number of threads within each inch on a nut, a bolt, or a fastener. To determine the TPI of a nut, either count the number of threads contained within an inch of length on the male fastener or use a thread checker on the nut. If the male fastener is less than an inch count ½” of an inch and x by 2
