Description

The Asimeto Ring Thread Gauge (GO) – Metric – Right Hand – 6g – M3 x 0.5 is a precision inspection tool designed for quality-conscious shops that routinely verify small metric threads. This GO gauge confirms the maximum material condition of M3 x 0.5 components, ensuring they meet the upper size limit during inspection and assembly.

  • Series: 683 Series, tailored for metric coarse 6g threads
  • Thread specification: Metric coarse 6g, right-hand thread, M3 x 0.5
  • Gauge type: GO ring gauge used to verify maximum material condition (upper limit)
  • Calibration: Precisely calibrated to ensure threading tolerance is met
  • Intended use: Ideal for quality control, inspection, and manufacturing environments requiring precise measurement
  • Handling features: Knurled outer edge for secure grip during inspection

Using the GO gauge allows quick, objective validation of part size at the upper tolerance limit, reducing guesswork and rework. A standardized GO check supports consistent pass/fail decisions across batches, helping sustain reliable threaded assemblies in precision manufacturing, electronics, automotive, and other engineering workflows. The metric M3 x 0.5 specification aligns with common miniature fasteners, enabling dependable verification in tight-tolerance applications.
