Description

The Asimeto GO ring thread gauge is a precision inspection tool built for metric coarse 6g threads, specifically M30 x 3.5. Designed for quality control, inspection, and manufacturing environments, it provides fast, reliable go/no-go verification to confirm parts meet the upper size limit.

  • Series: 683 Series — engineered for metric coarse 6g threads to ensure accurate, repeatable measurements.
  • Thread Specification: Right-hand GO gauge for M30 x 3.5 (6g) threads, calibrated to the upper tolerance limit.
  • GO Function: Verifies maximum material condition to ensure the part is within the allowable size at the upper limit.
  • Calibration: Precisely calibrated to deliver consistent pass/fail results across production runs.
  • Construction: Durable ring gauge with a knurled outer edge for secure handling and quick orientation on busy benches.
  • Applications: Ideal for quality control, inbound inspection, and on-the-floor verification where precise thread size checks are essential.

Using this gauge, teams can speed up inspection cycles, reduce scrap from out-of-tolerance parts, and gain confidence that M30 x 3.5, 6g threaded components will assemble correctly. Its robust construction and precise calibration make it a dependable addition to any metrology toolkit, especially where consistent upper-limit checks are critical.
