The JBO Thread Ring Gauge (NoGo) - Metric Fine - Left Hand - 6g - M28 x 2 is a precision tool designed to verify external metric threads with strict fine tolerances. Built for engineers, quality control teams, manufacturers, and workshop technicians, it provides quick, reliable acceptance or rejection of parts with M28 x 2 threads using a NoGo standard. Its left-hand configuration supports specialized applications where left-hand threads are used.

Crafted from hardened steel, this gauge delivers exceptional durability and wear resistance, maintaining accurate measurements even in busy environments and through repeated use. The robust construction helps preserve calibration and reduces the need for frequent replacements, making it a dependable addition to any metrology toolkit.

• Precise metric fine threading (M28 x 2, 6g): Ensures consistent, accurate external thread verification against strict tolerances, reducing guesswork and rework on threaded parts.
• Hardened steel construction: Provides long-lasting durability and wear resistance in demanding shop conditions, helping you maintain calibration over time.
• Intuitive NoGo design for fast inspection: Delivers quick pass/fail indication for non-conforming threads, speeding up quality checks and keeping production moving.

Used in routine inspection, this gauge helps standardize thread verification, minimizes downtime, and supports reliable engineering and procurement decisions. With its precise fit and rugged build, it’s a trustworthy choice for ensuring thread integrity across assemblies and components.
