The JBO Thread Ring Gauge (NoGo) — Metric Coarse, Right Hand, 4h, M1.8 x 0.35 — is a precise reference tool for validating external thread diameters. Designed for quality control teams, machinists, engineers, and workshop technicians, it helps quickly confirm whether a component’s coarse metric threads conform to the specified limits without guesswork.

Crafted from hardened steel for long wear resistance, this gauge withstands daily use in busy environments. The knurled edge provides a secure grip for fast, repeatable testing, and its NoGo design delivers clear indications of non-conforming threads during inspection.

• Immediate Go/No-Go verification: Quickly assess external thread diameters against the M1.8 x 0.35 coarse, right-hand (4h) specification, enabling fast, objective pass/fail decisions and reducing inspection time.
• Durable hardened steel construction: Built to withstand daily use in demanding environments, delivering long tool life and consistent performance with minimal wear.
• Ergonomic, easy-grip design: Knurled outer edge and clear handling cues make testing straightforward, even in tight spaces or with gloved hands.

This gauge streamlines your quality-control workflow by providing reliable, repeatable results, helping you verify fit and function of metric coarse threads quickly. By reducing guesswork and rework, it supports faster production cycles, better supplier confidence, and consistent results across parts and batches.
