The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. It targets right-hand threads in the 6G class with a size of M17 x 0.75, helping machinists, inspectors, and assembly teams verify threaded holes quickly and accurately.

With its Go/No-Go design, it delivers fast, confident checks that tell you in seconds whether a hole will accept a mating part, reducing guesswork and rework in production and maintenance tasks.

• Go/No-Go Quick-Checks: Instantly determine if the threaded hole meets spec by showing clear go or no-go results, speeding inspections and improving consistency across parts.
• Metric Fine-Thread Precision (M17 x 0.75) for Right-Hand Threads: Specifically tuned to metric fine threads, this gauge provides reliable checks for M17 x 0.75 with the right-hand orientation, ensuring accurate sizing without risk to components.
• Hardened Steel Durability: Built from hardened steel to resist wear, maintain accuracy through high-volume use, and stand up to daily shop conditions.

This plug gauge helps you speed up quality-control workflows, reduce downtime from threading mismatches, and improve overall assembly reliability. By delivering clear, repeatable go/no-go results, it supports better part qualification, tighter process control, and more consistent fit between parts.
