The JBO Thread Plug Gauge is a precise, go/no-go tool designed to verify UNF threaded holes quickly and reliably. Sized No. 8 x 36 and configured as Right Hand, 2B, it provides an accurate check for parts and assemblies across manufacturing, automotive, and aerospace environments.

This compact gauge is built for busy work cells, QA benches, and repair shops where fast, trustworthy thread verification matters.

• Go/No-Go design for fast conformity checks: Quickly confirm whether a hole accepts the plug (go) or is out of tolerance (no-go), reducing inspection time and rework.
• UNF compatibility with No. 8 x 36 sizing: Precisely matches UNF threads in the No. 8 x 36 size and 2B class to ensure consistent, repeatable results.
• Ergonomic, durable construction: Knurled grip and robust end fittings enable secure handling and long life in demanding environments.

Using this gauge transforms thread inspection from guesswork into a straightforward pass/fail check, helping you speed up quality control, reduce waste, and ensure proper fit for critical assemblies. Its simple operation supports both seasoned inspectors and new technicians, delivering reliable results across batches and shifts.
