The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. It provides a reliable Go/No-Go method to verify threaded holes quickly and accurately, making it ideal for machining, assembly, and quality control environments where tight tolerances matter.

Designed for left-hand M26 x 1 threads with a 6H tolerance, the gauge is built from hardened steel to withstand frequent use and resist wear. By using this gauge, you can confirm fit, reduce rework, and ensure parts assemble correctly the first time.

• Go/No-Go quick verification: Quickly determine if the hole meets the size spec with a clear pass/fail check, speeding inspections and reducing guesswork.
• Left-hand metric fine-thread compatibility: Specifically tailored for M26 x 1 left-hand threads with 6H tolerance, ensuring accurate gauging of critical holes.
• Hardened steel construction for durability: Built to endure daily workshop use, providing long-lasting performance and maintained accuracy over time.

This plug gauge helps you streamline quality control, reduce downtime, and ensure reliable, consistent results across assemblies. Its robust design and precise threading make it a dependable choice for engineers, machinists, and purchasing teams aiming for efficient, accurate thread inspection in demanding applications.
