The JBO Thread Plug Gauge is a precision tool crafted for metric fine threads, designed to streamline inspection of threaded holes. Its Go/No-Go design lets you quickly verify whether a hole meets the required tolerance, helping ensure parts fit together reliably. This left-hand configuration is tailored for M35 x 1.5 threads with a 6H tolerance, making it a practical choice for engineers, machinists, and maintenance technicians.

Built for daily use, the gauge features a hardened steel body that stands up to wear and repeated handling in busy workshops. The knurled grip provides secure, comfortable handling, so you can perform consistent checks with confidence, even in tight or awkward work areas.

• Go/No-Go fast inspections: Instantly determine pass/fail status of threaded holes, reducing inspection time and downtime while improving throughput.
• Hardened steel, long-lasting durability: Durable construction resists wear and maintains measurement stability through extensive use.
• Precisely matched for M35 x 1.5, 6H metric fine threads: Ensures accurate checks for the exact thread size and tolerance required in your assemblies.

This plug gauge helps you accelerate setup, minimize rework, and achieve consistent results across production runs. With its dedicated metric fine-thread focus and rugged build, it’s a reliable, repeatable tool you can trust for accurate thread verification.
