The JBO Thread Plug Gauge is a precision tool for metric fine threads, specifically calibrated for M34 x 1.5 right-hand threads. It's ideal for engineers, machinists, inspectors, and maintenance technicians who need fast, reliable checks to ensure threaded holes accept the correct mating parts.

With a Go/No-Go design and 4H tolerance, this gauge provides clear, decisive validation of hole threads, helping you maintain tight quality control. The hardened steel construction stands up to daily workshop use, delivering consistent performance over time.

• Go/No-Go quick validation for metric fine threads: The Go/No-Go design lets you quickly confirm whether an M34 x 1.5 threaded hole meets specification, reducing guesswork and speeding assembly.
• Right-hand orientation with 4H tolerance: Engineered for right-hand threads and 4H tolerance to support consistent, reliable fits with standard mating parts.
• Durable, hardened steel construction: Hardened steel provides long life and resistance to wear in busy workshops, maintaining accuracy through repeated checks.

Using this plug gauge streamlines thread inspection, enabling quick decision-making during assembly, reducing rework, and ensuring consistent, reliable fits across components. It supports quality control processes, speeds up maintenance checks, and gives technicians confidence that their threaded holes meet exact specifications every time.
