The JBO Thread Ring Gauge GO for metric fine threads is a precision inspection tool designed to verify external thread diameters quickly and reliably. Ideal for machining shops, quality control labs, maintenance teams, and assembly lines, it helps confirm that components conform to exact thread specifications—specifically left-hand M11 x 1 threads—without guesswork at the inspection bench.

Crafted from hardened steel, this GO gauge offers excellent wear resistance and long service life in demanding environments. Its carefully engineered geometry provides a clear, repeatable reference so you can identify conforming parts at a glance and keep production moving smoothly.

• Precision GO gauge for metric fine threads: Accurately validate external thread diameters against the M11 x 1 standard with a clearly defined GO limit, enabling fast pass/fail checks and reduced inspection time.
• Left-hand thread compatibility: Specifically designed for left-hand M11 x 1 threads, ensuring correct orientation and reliable measurements in non-standard assemblies.
• Hardened steel construction for durability: Built to withstand daily shop floor use, resisting wear and maintaining accuracy through long service life.

This gauge helps streamline quality control by delivering quick, confident thread checks, reducing rework and downtime, and ensuring consistent, high-quality mating with other components. With its robust construction and precise GO reference, you can trust your thread measurements across batches, equipment setups, and routine maintenance—saving time and improving overall manufacturing performance.
