The JBO Thread Plug Gauge (NoGo) – Metric Fine is a precision inspection tool designed specifically for metric fine threaded holes. It helps ensure threaded components meet the required size limits, delivering fast, reliable checks for quality control across manufacturing, machining, and maintenance environments.

Sized for M45 x 2 with 4H, right-hand threads, the gauge is built to endure daily use. A hardened steel core and knurled surface resist wear while providing a secure grip, so you can rely on accurate measurements even in busy workshops.

• NoGo metric fine thread verification: Quickly confirms that the hole's maximum size for metric fine threads (M45 x 2, 4H, right-hand) is not exceeded, enabling fast pass/fail decisions and reducing rework.
• Durable hardened steel body with knurled grip: Built to withstand daily use in challenging environments; corrosion-resistant finish and a non-slip grip support precise handling and long service life.
• Easy, repeatable use: Designed for straightforward insertion and withdrawal with consistent readings, minimizing operator variance and helping teams maintain process reliability across shifts.

Using this gauge speeds up inspections, minimizes downtime, and improves consistency across parts and operators. Its precise dimensions and rugged construction translate to faster decision-making, fewer rejects, and greater confidence in production quality—especially for critical metric fine threading across automotive, aerospace, and general manufacturing applications.
