The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. Its Go/No-Go design lets you quickly verify threaded holes, helping ensure parts fit together with confidence. Built in the Right Hand, 6H, M2.5 x 0.25 specification from hardened steel, it delivers reliable, long-lasting performance in busy workshops.

• Go/No-Go quick checks: Rapidly verify metric fine threaded holes to confirm correct size and tolerance, reducing guesswork and rework in assemblies.
• Hardened steel construction: Designed for durability and long tool life, resisting wear in daily shop use and demanding environments.
• Right-Hand, 6H design for standard metric threads: Ensures reliable, repeatable checks on common internal threads like M2.5 x 0.25, delivering consistent results in production workflows.

Executives, engineers, machinists, and inspectors will appreciate how this gauge simplifies thread verification. With a sturdy, knurled body and a precise Go/No-Go check, you can move from measurement to action with confidence, shorten setup times, and maintain high-quality standards across your projects.
