Description

The JBO Thread Plug Gauge (GO) - Metric Coarse - Right Hand - 6H - M56 x 5.5 is a precision go gauge designed to verify metric coarse threaded holes quickly and reliably. It's ideal for quality control teams, assembly lines, and engineering shops that depend on consistent thread fit.

Crafted from hardened steel for lasting durability, this GO gauge is built to withstand the rigors of busy workshops. Its right-hand configuration, paired with the 6H tolerance for M56 x 5.5 coarse threads, provides straightforward, repeatable checks that confirm holes meet standard thread specifications without guesswork.

  • Fast, go/no-go verification: Quickly confirm holes meet the M56 x 5.5, 6H coarse-thread standard to keep production moving and reduce guesswork during inspections.
  • Durable hardened steel construction: Designed to endure daily use in demanding environments, resisting wear to maintain accurate measurements over time.
  • Specifically calibrated for metric coarse right-hand threads: Ensures reliable, repeatable checks for common coarse-thread applications, helping maintain consistent assembly quality.

With the JBO GO Gauge in your toolkit, inspections become faster and more dependable. It supports tight tolerances on threaded holes, reduces rework, and helps you achieve consistent results across batches, delivering confidence in every assembly that relies on M56 x 5.5 coarse threads.
