The JBO Thread Plug Gauge is a precision Go/No-Go gauge designed for metric fine threads, specifically M32 x 1 with a 4H hole tolerance. It’s ideal for engineers, machine shops, quality inspectors, and assembly technicians who need fast, reliable verification that threaded holes will accept the mating bolt or insert without guesswork. The right-hand orientation and dual-end design allow quick checks in tight or awkward spaces, helping your team confirm correct sizing before costly assembly steps.

• Go/No-Go quick-check: Quickly confirm whether an M32 x 1 hole meets the 4H tolerance, delivering a clear pass/fail result to speed up inspections and prevent mismatches.
• Hardened steel construction: Built to withstand daily use in busy workshops, resisting wear and corrosion for dependable accuracy over time.
• Ergonomic right-hand design: Knurled grip and accessible ends support confident handling and repeatable measurements, even in confined work areas.

This plug gauge supports a streamlined quality-control workflow by delivering consistent, reliable results that reduce inspection time and rework. With its robust construction and precise tolerances, you can trust it to protect fit integrity across production runs and assemblies, enhancing overall threading reliability and confidence in every part you produce or assemble.
