The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M18 x 1 is a precision inspection tool designed to verify external thread diameters on fasteners and threaded components. It’s ideal for machinists, quality teams, and assembly professionals who need a reliable reference to confirm parts meet the M18 x 1 fine-thread specification and the 6g tolerance class.

Crafted from hardened steel for durability, this gauge delivers long-lasting performance in demanding workshop environments while resisting wear from daily use. Its compact, straightforward design allows for quick, unambiguous checks, helping you identify non-conforming parts at a glance and keep production flowing.

• Precise M18 x 1 Fine-Thread NoGo Check: Quickly confirms that external threads do not exceed the maximum limit for the 6g tolerance, enabling fast pass/fail decisions during in-process and final inspections.
• Hardened Steel Construction: Built to endure daily shop use with excellent wear resistance, delivering a long service life and reduced replacement needs.
• User-friendly Right-Hand Metric Fine Thread Design: Optimized for common right-handed fasteners and metric fine pitches, helping operators read measurements quickly and achieve repeatable results.

Integrating this gauge into your quality-control workflow saves time by delivering rapid, repeatable checks, reduces scrap from out-of-tolerance parts, and supports consistent thread quality across batches. With reliable results you can trust, you’ll experience smoother inspections, faster decision-making, and greater confidence in meeting precise engineering specifications.
