The JBO Thread Plug Gauge is a precision tool designed to verify threaded holes to Unified Thread Standards. Sized for right-hand 1 1/8 x 8 threads with a 2B tolerance, it’s ideal for quality teams and machinists across manufacturing, automotive, and aerospace environments.

The go/no-go design lets you identify conforming versus non-conforming threads at a glance, reducing inspection time and rework while supporting proper fitment and reliable performance.

• Go/No-Go at a glance: The dual ends allow quick pass/fail checks against the UNS 1 1/8 x 8 Right-Hand 2B specification, enabling fast, unambiguous quality decisions.
• Precision size and tolerance: Carefully matched to UNS 1 1/8 x 8 Right-Hand 2B, ensuring consistent measurements and repeatable results across parts and batches.
• Rugged, ergonomic build: Durable metal construction with a knurled grip resists wear and provides secure handling in busy shop environments, even with gloves.

Using the JBO Thread Plug Gauge in your inspection workflow delivers faster, more confident checks, reduces downtime, and helps ensure every part will thread in smoothly. Its durable design and straightforward Go/No-Go feedback support reliable quality control across manufacturing, automotive, and aerospace applications.
