The JBO Thread Ring Gauge (NoGo) is a precision tool designed for quick, reliable verification of external threads. Ideal for engineers, machinists, quality inspectors, and workshop personnel, it provides a clear pass/fail check to ensure parts meet exact size and threading specifications using the NoGo approach.

Configured for metric fine threading, this gauge features an M65 x 2 size with a left-hand thread and a 6g tolerance class. Crafted from hardened steel, it delivers durable, long‑lasting performance in demanding shop environments, maintaining accuracy even after repeated use.

• Exact Metric Fine M65 x 2 Left-Hand: Precisely matches the specified size and left-hand orientation, enabling accurate verification against your exact component requirements.
• Durable Hardened Steel Construction: Built to withstand daily inspection routines, resisting wear and maintaining dimensional integrity over time.
• Fast NoGo-Based Inspection: Provides quick, definitive go/no-go results to identify oversized or out-of-spec threads, reducing inspection time and handling of non-conforming parts.

Using this gauge helps streamline quality control, shorten setup and inspection times, and deliver consistent, dependable results across production runs. It supports confidence in fit and function for threaded assemblies, minimizes rework, and keeps your workflow moving smoothly from inspection to assembly.
