The JBO Thread Ring Gauge (NoGo) is a precision inspection tool for verifying external thread diameters on fasteners and machined parts. Designed for metric fine threads, this right-hand gauge supports M50 x 1 with a 6h reference to help ensure components meet exact specifications before assembly or mating with mating parts.

Made from hardened steel, the gauge delivers durability and wear resistance for long service life in busy workshop environments. Its carefully finished surfaces maintain accuracy across repeated checks, even in demanding production lines.

• Fast Go/No-Go checks for M50 x 1 metric fine threads: Quickly determine if a part’s external thread diameter is within tolerance, speeding up QC decisions and reducing bottlenecks on the line.
• Hardened steel construction for lasting accuracy: Built to resist wear in busy environments, preserving precise measurements and minimizing re-inspection over time.
• Clear markings and intuitive design: Simple, reliable identification of non-conforming parts, lowering misreads and rework while improving workflow consistency.

By using the JBO Thread Ring Gauge, teams can verify thread compatibility with confidence, streamline inspections, and ensure consistent results across batches. Its robust build and straightforward operation support reliable quality control and faster onboarding for new operators.
