JBO Thread Plug Gauge (NoGo) – Metric Fine, Right Hand, 4H, M50 x 2 is a dedicated inspection tool designed to validate metric fine threaded holes. Specifically built for machinists, quality engineers, inspectors, and workshop technicians, this NoGo plug gauge helps you quickly confirm whether a hole is within the permissible size and pitch. Constructed from hardened steel for durability, it delivers reliable readings in busy shop environments.

Metric Fine design focuses on the exact thread form you use, reducing guesswork during setup and ongoing quality checks. The NoGo specification provides a clear pass/fail standard that helps keep production moving and parts consistent across batches.

• NoGo verification for quick, reliable checks: Efficient pass/fail checks avoid rework and ensure consistent hole acceptance across batches.
• Metric Fine, M50 x 2 thread compatibility: Designed specifically for metric fine thread holes, including M50 x 2, ensuring accurate reading of size and pitch.
• Rugged hardened steel with knurled grip: Built to withstand daily shop use, with wear-resistance and a textured grip for steady handling and precise measurements.

Whether you're calibrating tooling, inspecting incoming components, or performing in-process checks, this gauge provides precise, repeatable readings you can trust. Its hardened steel construction withstands demanding environments, while the right-hand 4H NoGo specification ensures compatibility with your existing thread gauges and standard practices.
