Series Features

  • Quickly and automatically checks threaded holes (or external threads) by powering a Thread Gage Member into (or onto) and out of (or off of) the part. Versions are capable of “GO” gaging, “NO GO” gaging, and Combination gaging.
  • Sensitive high speed drive allows the Thread Gage Member to stop in case of missing or improperly formed threads. This registers a fault, creating a “reject” signal.
  • Spring-loaded spindle prevents damage to end of thread at start of engagement.
  • Will check blind holes accurately for thread depth.
  • Will not jam or stick in undersize (reject) threads. In automated applications, rejects can be separated out without stopping the process.
  • Does not subject the part (or the spindle) to high force or torque levels…even with a reject.
  • Quick to set up and use. Shipped pre-programmed. Will mount in any orientation.
  • Inspects a wide range of threads, with gage member replacement the only changeover. The toolholder allows for quick change-out of Thread Gage Members.
