The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. It helps ensure threaded holes in components accept fasteners with exact fit, supporting quick, confident quality checks on every part. The Go/No-Go design lets you verify both the major dimension and the thread pitch in seconds, so you can move forward with assembly without guesswork.

Built for M22 x 1 right-hand threads and manufactured to a 4H tolerance, this gauge is tailored for industries that demand consistent, repeatable results. The hardened steel construction stands up to daily use in busy workshops, resisting wear and maintaining accuracy over time.

• Go/No-Go Quick Verification: Quickly confirm hole size and thread pitch with a single check, speeding setup and reducing rework.
• Metric Fine Thread Compatibility (M22 x 1) Right-Hand: Specifically matched to M22 x 1 right-hand threads and 4H tolerance, ensuring reliable fits with standard components.
• Durable Hardened Steel Construction: Resists wear in high-use environments, maintaining accuracy and reducing replacement costs over time.

Using this gauge, inspectors and machinists can quickly verify that threaded holes meet required tolerance, improving throughput and preventing misfits. Its durable construction and precise Go/No-Go design give confidence in every measurement, helping you maintain quality across batches and cut costly rework.
