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?

  • Ok, well, maybe there is something some of your can debate about with me, thats fine, I don't know it all, thats for sure. 99% of the time, those tru pos things are a huge waste of money and time.

    One, there is usually no reason for ridiculously close tp needs on a threaded hole. Thanks to Over-Engineers. Even with a fine thread, the accuracy cannot be too close.

    Measuring a threaded holer properly, with the correct diameter ball and the correct settings and enoughpoints will get you as accurate as using a Tru Pos.

    The cost of a tru-pos, together withthe time consumed screwing and un screwing them, just boggles my mind as to why one would use them...
