The JBO Thread Plug Gauge is a precision tool designed to verify metric fine-thread holes quickly and reliably. Specifically crafted for right-hand M33 x 0.75 threads, this Go/No-Go gauge helps inspectors and machinists confirm proper fit without guesswork.

• Go/No-Go quick acceptance: A simple pass/fail check lets you confirm whether a hole meets the M33 x 0.75 fine-thread specification in moments, speeding up quality checks and reducing trial-and-error fits.
• Hardened steel construction: Built for durability, the hardened steel body resists wear from repeated use, preserving accuracy across production runs and tough workshop environments.
• Right-hand, metric fine thread format: Calibrated for M33 x 0.75 with 6H tolerance in a right-hand configuration, delivering reliable, repeatable hole verification for critical assemblies.

In practice, this gauge speeds up acceptance testing, reduces guesswork in assembly, and supports consistent results across shifts and production runs. With its hardened-steel construction and precise 6H tolerance on M33 x 0.75 right-hand threads, you can trust measurements from first part to last.
