The JBO Thread Ring Gauge (NoGo) — Metric Fine, Right Hand, 6g, M68 x 1 — is a precision inspection tool designed to verify external thread diameters and pitches on fasteners, fittings, and machined components. It helps teams in manufacturing, quality control, engineering, and maintenance quickly determine whether a part meets the M68 x 1 specification and stays within tolerance.

Built from hardened steel for outstanding durability, the gauge resists wear in busy workshops and long inspection cycles. The knurled outer edge provides a secure grip for fast, confident handling, even when you’re wearing gloves.

• Precise metric Fine NoGo gauge (M68 x 1, Right Hand): machined to exact tolerances to reliably show if external threads exceed the maximum size, enabling fast, objective pass/fail decisions during inspections.
• Hardened steel construction: delivers long tool life and excellent wear resistance in demanding environments, reducing replacement and maintenance costs.
• Ergonomic, user-friendly design: knurled edge and straightforward use support quick checks, minimize training needs, and help you keep inspection workflows moving.

Using this gauge helps you maintain consistent thread quality across parts and production runs, quickly screen out out-of-spec components, and reduce rework and downtime. Its precise dimensions and rugged construction translate into reliable, repeatable results you can trust for quality control, manufacturing, and maintenance applications.
