Accurate Metric Thread Ring Gauge M56.0 GO and NOGO Thread Machining Center for Checking
Metric thread ring gauges are precision inspection tools used for checking the thread of outside diameter on screws, bolts and threaded rods. These gauges typically have normal accuracy classifications including 6g, 6h, 7g, 7h, 8g, and 8h.
Our facility utilizes first-grade thread machining centers and measuring equipment to provide high precision thread ring gauges to customers worldwide.
GO and NOGO Functionality
Thread ring gauges come in GO and NOGO types. The GO ring gauge is machined to a minus tolerance, verifying the maximum material limit of externally threaded components. The NOGO thread ring gauge is machined to a plus tolerance, verifying the minimum material limit.

Applications
These threaded ring gauges are primarily used to measure thread diameter and pitch with high precision. Their wide measurement range and simple operation make them ideal for machinery manufacturing, aerospace, automotive production, and other industrial applications.
Usage Precautions
- Avoid touching the working surface with bare hands to prevent rust
- Store properly on tool cabinets or wooden backing plates - never on machine tool holders or guide rails
- Inspect regularly for damage, rust, or deformation
- If rust appears, soak in gasoline, wipe carefully, and apply anti-rust oil
- Never store working surfaces together to prevent sticking
- Always clean and store in dry conditions after use
