JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. It uses a simple Go/No-Go design to quickly validate threaded holes, helping ensure mates fit correctly in M11 x 0.5 right-hand applications (4H). Built for durability on the shop floor, the gauge features hardened steel construction that resists wear and stands up to repeated use in demanding environments. Ideal for engineers, machinists, quality inspectors, and maintenance technicians who need fast, reliable hole checks.

• Go/No-Go quick checks for metric fine threads: Quickly validate hole size acceptance (M11 x 0.5) with clear pass/fail cues, speeding setups and reducing guesswork in assembly.
• Hardened steel construction for durability: Built to withstand daily use on the shop floor, delivering long-lasting accuracy and wear resistance through busy production runs.
• Ergonomic, knurled grip for easy handling: Provides secure, comfortable handling and precise alignment, so you can insert and read gauges quickly with less finger fatigue.

With JBO’s Go/No-Go metric fine thread gauge, you can shorten inspection times, minimize rework, and improve consistency across operators. The combination of a purpose-built M11 x 0.5 gauge and robust steel construction gives you reliable performance year after year, supporting tighter quality control and smoother assembly workflows.
