Tru-Pos Locators UNJF thread

Need to measure some threaded holes 1/4-28 UNJF.
Anyone know where I can find plugs for this thread to check location?

  • I would get the correct socket cap screw and get it turned down on a lathe (the head) screw it in and check it as a stud. like previously stated too many variable using the pitch... or just measuring the minor Ø anyways with that, not truly the threaded hole location. and whos to say all the threads start in the same spot on every part???
