The JBO Thread Plug Gauge in a right-hand Go-No/Go configuration provides fast, reliable verification of threaded holes to exact Unified thread standards. Designed for use across manufacturing, automotive, and aerospace environments, this gauge helps inspectors confirm whether a threaded hole accepts the correct thread size and pitch with confidence.

Its straightforward Go/No-Go design lets you quickly distinguish conforming threads from non-conforming ones, reducing guesswork and rework while speeding up quality checks on busy production lines.

• Fast Go/No-Go Verification: Instantly confirms thread conformity against standard sizes, cutting inspection time and improving first-pass yield on the shop floor.
• Right-Hand Pg 21 x 16 Compatibility: Precisely matched to the Pg 21 x 16 right-hand thread, ensuring accurate readings and reliable hole inspection every time.
• Rugged, Ergonomic Design: Knurled, durable construction with corrosion-resistant fittings delivers comfortable handling and long service life in demanding environments.

This plug gauge supports streamlined quality control by delivering clear, binary results that maintenance teams and auditors can trust. By verifying threaded holes meet the correct size and pitch, it enhances fitment with mating parts, reduces downtime from misfits, and promotes consistent performance across assemblies in manufacturing, automotive, and aerospace applications.
