The JBO Thread Plug Gauge (GO) is a precision go gauge designed to verify threaded holes to exact metric specifications. It’s ideal for machinists, quality teams, and maintenance technicians, providing a quick, reliable way to confirm that M52 x 2 right‑hand threads in tapped holes meet the required size and pitch.

Crafted from hardened steel, this GO gauge offers exceptional durability and wear resistance for demanding workshop environments. Its straightforward, robust design makes it easy to identify properly threaded holes, supporting accurate quality control and faster inspections.

• Metric Fine M52 x 2 compatibility (Right-Hand): Verifies internal holes conform to the exact M52 x 2 fine-pitch specification with a reliable Go check, helping you accept or reject parts quickly.
• Hardened steel construction: Delivers outstanding wear resistance and long service life, even in high-volume production scenarios.
• Ergonomic knurled handling: Provides a secure grip and quick, repeatable insertion for fast, consistent inspections.

Using the GO gauge streamlines inspections, reduces guesswork, and speeds up quality assurance by delivering clear, repeatable results. Its durable build means fewer tool replacements over time, helping maintain smooth workflows and reliable sizing across batches.
