The JBO Thread Plug Gauge is a precision inspection tool designed to verify threaded holes against Unified thread standards. Engineered for right-hand threads in size 11/16 x 16 and 2B tolerance, this gauge helps ensure accurate, reliable measurements across a range of parts and assemblies. Its meticulous design and precise dimensions support efficient inspections in manufacturing, automotive, and aerospace applications.

Designed for engineers, inspectors, machinists, buyers, and hobbyists alike, this go/no-go gauge makes it quick and easy to determine whether threads are within spec, helping you prevent misfit parts and costly rework.

• Go/No-Go quick-check design: Instantly determine thread conformance—the go end seats within tolerance while the no-go end reveals out-of-spec conditions, delivering fast, reliable verification and reducing inspection time.
• UNS right-hand 11/16 x 16, 2B standard: Precisely sized to match Unified Thread Standards, ensuring compatibility with common holes and assemblies and simplifying quality control across suppliers and customers.
• Ergonomic two-end construction with knurled grip: Easy handling in busy work environments, with distinct ends for go and no-go checks that speed inspections without added tools or guesswork.

Using the JBO Thread Plug Gauge helps your team verify thread readiness quickly, cut inspection time, and prevent costly assembly errors. The clear go/no-go workflow supports consistent results across batches, improving workflow efficiency and overall part quality.
