A Gewinde-Grenzlehrdorn is a combination of a Gutlehrdorn and an Ausschusslehrdorn. The Ausschuss side is marked with a red ring. The Gut side should screw into the cut thread of a workpiece by hand without extra force. If it doesn't, the thread doesn't meet the required standards (Ausschuss). The Ausschuss side should only screw in up to two turns by hand. If it goes further, the thread doesn't meet the required standards. The reference temperature for the parts and gauges is 20°C. VÖLKEL can provide a factory calibration certificate upon request. The calibration is done in an independent lab following the specified standards (DIN, ISO, ANSI) on IAC-Gewindescanners.

  • Gewinde-Grenzlehrdorn Definition: A combination of a good and a reject gauge
  • Testing the Good Side: The good side of the gauge should screw into the cut thread of a workpiece by hand without excessive force
  • Testing the Reject Side: The reject side should not screw in more than two turns by hand without excessive force
  • Reference Temperature: Both workpieces and gauges are referenced at 20°C
