The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for metric fine-threaded holes. It helps engineers, machinists, and quality teams quickly verify M2.5 x 0.2 threads and ensure parts assemble smoothly. The compact, right-hand gauge is built for real-world work environments, with a hardened steel body and a knurled grip for secure handling, plus color-coded collars that aid quick orientation.

This gauge is purpose-built for tight tolerance work, delivering reliable checks without guesswork. Its Go/No-Go design lets you confirm acceptance or rejection of bores in seconds, supporting fast, confident decisions in production or inspection settings.

• Go/No-Go quick thread check: Instantly confirm whether a hole meets the M2.5 x 0.2 specification, speeding up quality control and reducing assembly guesswork.
• Metric fine-thread accuracy (M2.5 x 0.2) with 4H tolerance: Precisely sized to the metric fine-thread standard, enabling reliable, repeatable checks across production runs.
• Hardened steel construction with ergonomic knurling and right-hand threading: Durable, wear-resistant body with a secure grip for reliable use in right-hand thread assemblies; color-coded collars aid end orientation and quick identification.

With this gauge in your toolkit, you can verify threaded holes in seconds, shorten inspection times, and ensure consistent results across parts and teams. Its rugged construction and precise metric fine-thread sizing support smoother assemblies, fewer reworks, and a dependable quality assurance workflow.
