Description
The JBO Thread Plug Gauge is a precision Go/No-Go tool crafted for metric coarse threads. It’s the reliable choice for inspectors, machinists, engineers, and assembly technicians who need fast, accurate checks of threaded holes to ensure proper fit and function. Designed for right-hand applications, this gauge verifies holes sized M1.1 x 0.25 with a 5H tolerance, helping you prevent mismatches before they hit production or assembly.
- Go/No-Go ends for fast, decisive checks: Quickly confirm whether a hole accepts the plug gauge or stops at the no-go limit, delivering clear pass/fail results in seconds and reducing inspection time.
- Hardened steel with a knurled grip: Built to withstand daily shop use, resisting wear while providing a secure, comfortable grip for repeatable, accurate insertions and removals.
- Right-hand, metric coarse size (M1.1 x 0.25) with 5H tolerance: Precisely matched to common coarse-thread holes, ensuring reliable checks and compatibility with standard components and manuals.
Using this gauge supports a smoother workflow: validate thread holes before sub-assembly, catch sizing issues early, and maintain consistent results across batches. Its sturdy construction and straightforward Go/No-Go design give you confidence in every measurement, helping you reduce downtime and deliver precise, reliable assemblies every time.
