The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M85 x 1.5 is a precision inspection tool for external threads. It’s designed for engineers, machinists, quality inspectors, and manufacturing teams that need quick, reliable verification of thread diameters to keep parts within specification.

Crafted from hardened steel, this gauge delivers durable, wear‑resistant performance in demanding work environments. The metric fine size (M85 x 1.5) and right‑hand configuration are clearly marked to speed setup and help you quickly identify non‑conforming components.

• Accurate Metric Fine No-Go verification: Enables fast pass/fail checks for external threads on metric fine sizes, helping ensure components meet the M85 x 1.5 spec and catch out‑of‑tolerance parts before they move to the next manufacturing step.
• Hardened steel construction for long tool life: Built to resist wear and corrosion, maintaining stable, repeatable measurements through frequent use in busy shop environments.
• Easy-to-use design with clear markings: Right‑hand orientation and clearly labeled size speed inspections, reduce setup time and minimize misreads during quality control checks.

This gauge helps you streamline quality control workflows by delivering quick, dependable thread checks that translate into tighter tolerances and fewer reworks. With rugged construction and straightforward operation, it supports consistent results across shifts, boosts inspection throughput, and gives your team the confidence to move parts through manufacturing, assembly, or maintenance with minimal delays.
