The JBO Thread Plug Gauge (NoGo) – Metric Fine is a precision tool designed to verify internal threads in metric fine series. This NoGo plug gauge is specifically engineered for M55 x 2, right-hand threads, with a 6H tolerance class, helping inspectors confirm holes meet the lower end of the specified limits. Ideal for quality control in manufacturing, inspection, and maintenance environments, it provides fast, reliable checks that reduce guesswork.

Crafted from hardened steel, the gauge offers durability and wear resistance to withstand daily use in busy workshops. The knurled body and compact plug design provide a secure grip and precise handling, while the metric-fine specification ensures compatibility with common M55 x 2 threaded holes. This tool is built to maintain accuracy over time, even in demanding environments.
