The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6h - M13 x 0.5 is a precision tool for inspecting external thread diameters. Built for engineers, manufacturers, technicians, buyers, tradespeople, and hobbyists, it provides a fast, reliable GO check to verify that threads meet exact size and pitch specifications. Crafted from hardened steel for durability and designed for intuitive use, it helps ensure consistent, compliant results in busy work environments.

• Precise metric GO gauge for M13 x 0.5: Quickly verify external thread diameter and pitch to confirm conformance with the 6h tolerance in metric fine threads.
• Hardened steel, wear‑resistant construction: Built for durability in busy workshops, resisting wear and maintaining accuracy over many inspections.
• Intuitive, fast QC with clear pass/fail read: Simple at-a-glance checks that speed quality control and reduce inspection time on the shop floor.

It helps you streamline quality control by delivering fast, confident checks of external thread diameters. The rugged hardened steel body resists wear in busy shops, while the metric fine M13 x 0.5 sizing provides reliable, repeatable results across parts and assemblies. By enabling quick acceptance decisions, it supports efficient workflows, reduces rework, and helps you meet engineering and manufacturing standards with consistent performance over time.
