Description

The JBO Thread Plug Gauge (GO) is a precision inspection tool tailored for verifying threaded holes to Unified thread standards. Designed for right-hand threads in UNS sizes, it features a 1 5/8 x 12 dimension and a 2B specification, making it ideal for quality control in manufacturing, automotive, and aerospace environments. Use it to quickly confirm that a hole will accept the corresponding fastener and to identify any non-conforming threads before assembly.

  • Go gauge for fast conformance checks: Quickly determine whether threaded holes meet the UNS standard, enabling immediate pass/fail decisions and smoother inspection workflows.
  • Precise UNS Right-Hand 2B sizing (1 5/8 x 12): Exact dimensions provide consistent go/no-go results, reducing guesswork and rework across parts and batches.
  • Ergonomic, durable design with knurled handling: Knurled body enables secure grip and easy insertion, supporting repeatable, reliable checks in busy work environments.

By using the JBO Thread Plug Gauge (GO), you can streamline your quality checks, minimize downtime, and improve overall threading accuracy in your production and maintenance workflows. Its straightforward go/no-go action helps teams deliver consistently correct assemblies, protect tooling investments, and maintain high standards of reliability across critical applications.
