I ordered from China off the net a 1/4 20 butterfly nut, but it does not fit the 1/4 20 bolt on the tripod plate. Do I need a bigger nut size? I was under the impression the same size nut should fit. Any tips? Or is the ordered nut faulty?

    Did you seriously order a single nut from China? – null Oct 12 '16 at 17:42
  • Can you be more specific than "it does not fit"? Does it get difficult to turn after a few turns? Does it even start? Is the nut left-hand threaded? – scottbb Oct 12 '16 at 18:48
  • What sort of tripod plate? Some tripods use 3/8" screw thread. – vclaw Oct 12 '16 at 19:53
  • It's a 1/4 20 for sure. The nut does not even start! I think WayneF could be right. It may not have been UNC. – giorgio79 Oct 12 '16 at 20:35

    re null, yes I ordered a winged nut as I am in the EU, and did not find any UNC threads in the stores, only metric ones. – giorgio79 Oct 12 '16 at 20:36

From China, it may be metric then, or at least not 1/4-20 if it does not fit. 1/4-20 is the standard tripod screw thread, which should fit by definition.

Full name of thread is UNC http://en.wikipedia.org/wiki/Unified_Thread_Standard

If in North America, try the local hardware store.

  • Take the bolt along with you when you go to the store. This way you can try if the nut fits. – null Oct 12 '16 at 19:36
  • Thx, I am in the EU, and I tried a few stores, but they only have metric stuff. :) – giorgio79 Oct 12 '16 at 20:36

Most tripods are 1/4 and 20 UNC threads, but some bigger cameras have a 3/8ths and 16 UNC thread so tripods exist that have on their head. If what you're looking at though is the base of a tripod, i.e. just the legs and the top plate, but no ball mount or anything (what is often called the "head") then those are USUALLY 3/8. When you buy a tripod head, it has a 3/8 female at the bottom to connect to the actual tripod, then the 1/4 on the top to connect to the camera.
