- Hex Rod Coupler Coupling Nuts are internally threaded fasteners used to join two male threads, most commonly threaded rod. The outside of a coupling nut is typically a hex so it can be driven with a wrench. Coupling nuts are also used to make up long rod assemblies from shorter lengths of rods
- Also known as: Connection Nuts, Extension Nuts, Coupling Nuts
- Material / Coating: Zinc Plated is the most common fastener of plating due to its the low cost and shinny 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 isnt recommended if corrosion is a concern. If you want a fastener that will withstand the outdoor elements choose from our Stainless steel range
- 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. If the male fastener is less than an inch, measure 1/2", count how many there are then multiply the number by 2
- Difference between UNC v BSW Threads: UNC and BSW have the same thread per inch value, except for the 1/2" size. Theoretical it would be possible to interchange them as they have the same amount of threads per inch. However due to the difference in thread angle, the connection would not be as strong as when using the proper combinations
