The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 4h - M13 x 1 is a precision inspection tool designed to verify external thread diameters on fasteners, fittings, and machined components. Ideal for quality control teams, manufacturers, and workshop technicians, it provides a fast, reliable way to confirm components meet the M13 x 1 metric fine thread standard. NoGo gauges are used to identify non-conforming threads, helping keep assemblies within spec from the start.

Crafted from hardened steel, this gauge delivers durability and wear resistance for daily shop floor use. Its precise dimensions and robust construction ensure long-lasting performance in demanding environments, reducing downtime and the need for frequent replacements. The design also supports quick, intuitive checks—making it easy for operators of all skill levels to identify out-of-tolerance parts.

• Exact M13 x 1 Metric Fine NoGo profile: Delivers immediate pass/fail feedback for external threads, speeding up QC checks and reducing rework.
• Hardened steel construction: Built to last in busy environments, resisting wear and retaining accuracy across many cycles.
• Right-hand orientation with 4h tolerance: Aligns with standard right-handed thread specifications for consistent, reliable results on common components.

Using the JBO Thread Ring Gauge streamlines thread inspection, helping you quickly verify that parts meet the required threading standard. It supports a more efficient workflow, reduces scrap, and delivers repeatable, confident results across production runs.
