Thread Ring Gauge Class 6g Tolerance for Accurate Thread Checking
Wholesale Threads Ring Gauge High Precision Screw Gauge for Thread M30x1.50-6g GO with Calibration Certificate
Metric thread ring gauges are precision inspection tools used for checking the thread of outside diameter on screws, bolts and threaded rods. Available in standard accuracy grades including 6g, 6h, 7g, 7h, 8g, and 8h.
Our facility features first-grade thread machining centers and measuring equipment to provide high precision thread ring gauges to customers worldwide.Thread ring gauges come in GO and NOGO types. The GO ring gauge is machined to a minus tolerance for maximum material limit verification, while the NOGO gauge uses a plus tolerance for minimum material limit verification of externally threaded components.

Applications
Threaded ring gauges are primarily used to measure thread diameter and pitch. Their high precision, wide measurement range, and simple operation make them ideal for machinery manufacturing, aerospace, automotive manufacturing, and other industrial applications.
Usage Precautions
- Avoid touching the working surface with bare hands to prevent rust.
- Store properly on tool cabinet tables or wooden backing plates - never on machine tool holders or guide rails.
- Inspect regularly for damage, rust, or deformation.
- Treat rust by soaking in gasoline, careful wiping, and applying anti-rust oil.
- Never store working surfaces together to prevent adhesion.
- Clean thoroughly after use and store in dry conditions.
