The JBO Thread Plug Gauge is a precision inspection tool for metric fine threads, specifically M24 x 1. Its Go/No-Go design lets you quickly verify thread engagement and ensure proper mating with components. The left-hand configuration supports reverse-threaded applications common in industrial settings, while the hardened steel construction and knurled body provide durability and a secure grip for frequent checks.

• Go/No-Go quick verification: Quickly confirm thread engagement within tolerance to speed up assembly and reduce trial fits.
• Hardened steel durability: Hardened steel construction resists wear and maintains precision through daily shop use.
• Left-hand 6G precision: Specifically designed for left-hand thread inspection with 6G tolerance, delivering consistent go/no-go results across parts.

With the JBO Thread Plug Gauge, inspectors and machinists gain a reliable, fast method to verify hole readiness, minimize downtime, and improve first-time assembly success. Its robust build and ergonomic grip support frequent checks on busy shop floors, helping you maintain quality and throughput across projects that rely on precise M24 x 1 threads.
