Description

The JBO Thread Plug Gauge (GO) is a precision inspection tool designed to verify internal threads quickly and reliably. Crafted for UNS right‑hand threads with a 2B tolerance, this GO gauge helps ensure threaded holes will accept fasteners as intended. Its compact 2 x 8 configuration makes it a practical addition to routine quality checks in manufacturing, automotive, and aerospace environments.

  • Go gauge design for fast, confident thread verification: Quickly confirm whether threaded holes meet the required UNS specifications, reducing inspection time and preventing incorrect assemblies.
  • UNS right‑hand, 2B tolerance compatibility: Ensures reliable fitment with standard fasteners and consistent results across parts and batches.
  • Rugged knurled body for easy handling: Durable, slip‑resistant grip that maintains accuracy in busy shop conditions and repeated use.

Used by inspectors, machinists, and quality teams, this GO plug gauge streamlines dimensional checks, supports consistent quality, and helps prevent costly rework by catching nonconforming threads early in the production or assembly process.
