The JBO Thread Plug Gauge (NoGo) - Metric Fine - Right Hand - 4H - M50 x 1.5 is a precision inspection tool designed to verify threaded holes that use metric fine threads. It supports quick, confident go/no-go checks in machining, assembly, and quality control workflows.

Built to endure busy shop floors, this NoGo gauge uses hardened steel for wear resistance and long service life. The knurled body provides a secure grip, while the right-hand orientation aligns with standard inspection practices for fast, repeatable measurements.

• Metric Fine NoGo design for M50 x 1.5 threads (4H): Precisely sized to verify internal threads meet the 4H tolerance, helping you confirm hole quality and reduce guesswork during inspection.
• Hardened steel construction with knurled grip: Delivers durable wear resistance for continual use in demanding environments, with a secure, non-slip handle for accurate handling.
• Right-hand orientation and consistent dimensions: Easy to integrate into standard measurement setups, speeding checks and improving repeatability across inspections and shifts.

Using the JBO Thread Plug Gauge (NoGo) helps streamline quality control by delivering clear pass/fail results for M50 x 1.5 threaded holes. Its durable construction and ergonomic design support reliable, repeatable measurements, reducing downtime and boosting confidence in every threaded connection.
