The JBO Thread Plug Gauge is a precision tool designed for metric fine threads, ideal for quality control and precise assembly where thread size matters. With a right-hand orientation and 6H tolerance for M26 x 0.5 threads, its Go/No-Go design lets you quickly verify threaded holes and confirm that components fit together cleanly.

• Go/No-Go quick verification: The quick-check design speeds inspections of threaded holes, helping you confirm fit without guesswork.
• Metric fine-thread compatibility: Specifically engineered for M26 x 0.5 with 6H tolerance to ensure accurate hole gauging and consistent results.
• Hardened steel construction: Rugged, wear-resistant body delivers long service life under demanding shop conditions.

The Go/No-Go JBO Thread Plug Gauge helps you streamline inspection workflows, reduce downtime, and improve assembly reliability by providing fast, repeatable checks for hole size and thread fit. Built to withstand daily use in busy workshops, it supports consistent results across batches and minimizes rework or ambiguous fits.
