JBO Thread Plug Gauge - BSW Go/No-Go - Right Hand - Medium Class - 7/8 x 9

The JBO Thread Plug Gauge – BSW Go/No-Go – Right Hand – Medium Class – 7/8 x 9 is a precision inspection tool designed to verify threaded holes and mating components to British Standard Whitworth (BSW) specifications. Its compact, durable construction makes it a staple for manufacturers, automotive teams, and aerospace suppliers who rely on consistent thread quality.

Equipped with a clear Go/No-Go design, the gauge provides rapid pass/fail checks: the Go end should thread in smoothly within tolerance, while the No-Go end should not. This simple test reduces inspection time and helps prevent misfits in assembly.

• Go/No-Go Quick Conformity Check: Quick, deterministic verification of thread holes to ensure they meet the 7/8 x 9 BSW standard, reducing guesswork and rework.
• Durable, Ergonomic Construction: Knurled, corrosion‑resistant body provides a secure grip and long service life in busy shops, even with gloves on.
• Right-Hand, Medium Class Precision: Calibrated for standard right‑hand threads with a medium class tolerance, delivering repeatable results across production runs.

Using the JBO Thread Plug Gauge helps you speed up quality checks, improve fit accuracy, and maintain consistent results across batches. It supports faster decision-making in QA, minimizes downtime due to thread rejection, and gives your team a reliable tool for dependable assemblies.
