M80x1.5-6h Thread Ring Gauge Precision Internal Thread Measurement & Inspection

Thread Ring Gauge Precision Internal Thread Measurement & Inspection

Product Description

Metric thread ring gauges are precision inspection tools designed for checking the thread of outside diameter on screws, bolts, and threaded rods. These gauges typically feature normal accuracy classifications including 6g, 6h, 7g, 7h, 8g, and 8h.

Thread ring gauges are available 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 of externally threaded components.

Our facility utilizes first-grade internal thread machining centers and measuring equipment to provide high-precision thread ring gauges to customers worldwide.

Applications

Threaded ring gauges are primarily used to measure thread diameter and pitch. These precision tools offer high accuracy, wide measurement range, and simple operation, making them ideal for machinery manufacturing, aerospace, automotive manufacturing, and other industrial applications.

Precautions

Avoid touching the working surface of the plug ring gauge with bare hands to prevent rust.
Store the gauge on a stable surface like a tool cabinet or wooden backing plate, not on machine tool holders or guide rails.
Regularly inspect for damage, rust, or deformation. If rust appears, soak in gasoline, carefully wipe clean, and apply anti-rust oil.
Never store working surfaces of two plug ring gauges together to prevent adhesion and potential damage.
After use, clean thoroughly and store in dry conditions.
