The JBO Thread Ring Gauge (GO) is a precision tool used to confirm external thread diameters to exact metric standards. It’s designed for Go/No-Go checks on right-hand threads, including the M60 x 1 size with 6h tolerance, making it a practical choice for engineers, machinists, inspectors, and suppliers who require fast, reliable thread verification.

Crafted from hardened steel, this ring gauge resists wear in demanding environments and maintains calibration over time. The knurled outer edge provides a secure grip for easy placement and removal, while the smooth inner bore supports consistent measurements for quality control throughout production or maintenance workflows.

• Hardened steel construction for long life: Durably crafted to resist wear in busy shops, preserving accuracy through repeated inspections and calibration checks.
• Metric Fine external thread GO gauge for M60 x 1 (6h, Right Hand): Precisely calibrated to the M60 x 1 specification with 6h tolerance, enabling confident Go/No-Go verification of external threads.
• Ergonomic knurled grip for easy handling: The textured outer surface provides a secure grip and quick placement, speeding up inspection cycles and reducing handling errors.

By adding the JBO Thread Ring Gauge (GO) to your inspection toolkit, you gain a dependable method for verifying external threads, speeding up QC checks, and ensuring components meet the required standard before they move to the next production stage. Its robust construction and precise calibration help reduce rework, downtime, and returns, delivering confident, repeatable results across jobs and teams.
