The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric threads. Calibrated for metric fine threads in the M13 x 1 size with right-hand orientation, it helps engineers, machinists, buyers, and quality teams quickly confirm that parts meet exact size and tolerance requirements. The NoGo design provides a clear pass/fail indication to speed up inspections and reduce guesswork in routine quality checks.

Built from hardened steel, the gauge resists wear and corrosion for dependable performance in busy workshops. Its compact ring interface makes alignment straightforward, and its NoGo feature delivers unambiguous feedback to identify non-conforming threads at a glance.

• Precise metric fine external thread verification: Accurate no-go sizing for M13 x 1 right-hand threads (6e external thread tolerance) to ensure parts meet specification consistently.
• Durable hardened steel construction: Designed for long service life in demanding environments with excellent wear resistance and corrosion resistance.
• Fast, user-friendly inspection: Simple alignment and clear pass/fail feedback that reduces inspection time and training, helping you make quick, reliable quality decisions.

Using the JBO NoGo Thread Ring Gauge helps streamline quality control, reduce downtime, and ensure every threaded part meets its specification at a glance. Its robust construction and precise sizing translate into consistent results across production runs, giving you confidence when assembling, testing, or shipping components.
