Series Features

  • Quickly checks threaded holes (or external threads) by automatically screwing a Thread Gage Member into (or onto) the part.  “GO” gaging, “NO GO” gaging, and Combination gaging are all possible.
  • The TVU-SMNP features a spring-biased spindle with (adjustable) pre-set torque limits within the internal mechanism.
  • Will check blind holes or external threads accurately for thread length.
  • If the threads are missing, too short, or improperly formed, the Thread Gage Member will simply spin with the part. This creates a “reject” signal.
  • The drive “locks up” when the spindle is reversed, so that the gage will not stick in (or on) the thread when wrong-size (or short) threads are encountered.
  • Will withstand constant drenching with coolant.
  • Does not subject the part (or the spindle) to high force or torque levels.
