The JBO Thread Ring Gauge (GO) — Metric Fine, Right Hand, 6e, M20 x 0.75 is a go/no-go gauge designed for fast, confident verification of external metric threads. It serves engineers, machinists, quality inspectors, and maintenance teams who need reliable, on-the-spot checks to confirm thread size and fit.

Manufactured from hardened steel, this gauge delivers excellent wear resistance and long service life in demanding shop environments. Its simple ring design makes inspections quick and intuitive, helping you identify properly conformed threads at a glance.

• Fast, one-step Go/No-Go checks: Quickly determine if external threads meet the M20 x 0.75 specification with decisive feedback, reducing inspection time and downtime.
• Hardened steel construction for long service life: Built to withstand daily wear, resisting abrasion and preserving accuracy across many inspections.
• Metric Fine compatibility with right-hand threads: Precisely tuned to metric fine threads (6e, M20 x 0.75, right-hand) to deliver consistent, repeatable results across parts and lots.

With the JBO Thread Ring Gauge in your QA toolkit, you’ll streamline inspections, minimize rework, and ensure threaded components perform reliably in assemblies. Its durable build and precise design foster confidence in every check, helping your team speed up workflows and deliver consistent, high-quality results.
