The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. This right-hand Go/No-Go gauge quickly checks threaded holes to ensure they meet the M32 x 0.75 standard with a 6H tolerance, helping you verify fit before assembly.

Constructed from hardened steel for long-lasting performance, this gauge resists wear even with frequent use on busy production floors. The knurled body provides a secure grip for reliable handling, while the Go/No-Go design delivers fast, decisive checks—pass for in-tolerance holes, fail for out-of-tolerance ones—so you can keep work moving and reduce rework.

• Go/No-Go Quick-Check: Instantly determine if a threaded hole is within spec, speeding quality inspections and eliminating guesswork during assembly.
• Hardened Steel Construction: Built to endure repeated use with excellent wear resistance, preserving measurement accuracy over time.
• Ergonomic, Knurled Body: Easy, secure handling even in busy or glove-heavy environments, supporting consistent, repeatable measurements.

By delivering fast, accurate hole verification, the JBO Thread Plug Gauge helps maintain reliable thread engagement and improves workflow, reducing downtime and scrap while giving you confidence in every assembly that uses metric fine threads.
