JBO Thread Plug Gauge - Metric Fine Go/No-Go - Right Hand - 4H - M17 x 1.5

The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine-thread holes. Tuned specifically for M17 x 1.5 threads with a 4H tolerance and right-hand orientation, it’s ideal for engineers, machinists, inspectors, and workshop professionals who need reliable thread verification without guesswork. The Go/No-Go design enables quick, confident checks of fit, keeping production moving and ensuring components assemble correctly the first time.

• Go/No-Go Inspection Design: Two ends provide clear Go and No-Go limits, allowing rapid verification of thread engagement and hole size in a single check—reducing inspection time and rework.
• Hardened Steel Construction: Built to withstand daily use in busy shops, the durable, wear-resistant body maintains accuracy and resists corrosion over thousands of measurements.
• Precise M17 x 1.5 Fine Thread (4H) with Right-Hand Orientation: Specifically matched to the M17 x 1.5 fine-thread standard and 4H tolerance, the gauge delivers consistent, repeatable results that integrate smoothly with common manufacturing workflows.

Using the JBO Thread Plug Gauge simplifies quality checks and assembly planning. It helps you confirm hole readiness quickly, reduces misfits and downtime, and delivers dependable results across parts and suppliers. With its durable construction and precise thread specification, you can trust it to perform reliably in demanding environments and support efficient, accurate threading inspections.
