The JBO Thread Plug Gauge is a precision tool designed for metric fine threads, ideal for engineers, machinists, quality teams, and maintenance professionals who need quick, reliable hole inspection. Configured for 4H hole tolerances and a right-hand M16 x 1.5 thread, this Go/No-Go gauge delivers straightforward pass/fail checks to ensure parts fit together accurately.

• Go/No-Go Quick Checks: rapidly verify hole size and thread quality with a simple pass/fail test, reducing inspection time and preventing misfits in assemblies.
• Hardened Steel Durability: built from hardened steel to resist wear and maintain measurement accuracy through repeated use in busy shop environments.
• Right-Hand Metric Fine Thread Compatibility (M16 x 1.5): specifically designed for metric fine threads, ensuring precise checks for M16 x 1.5 right-hand holes aligned with 4H tolerances.

Using the JBO Thread Plug Gauge streamlines quality control, helping you move parts through inspection with confidence. The durable construction and precise Go/No-Go limits support consistent results across shifts, reducing downtime and rework while simplifying setup and daily use in metric fine-thread applications.
