Thread Ring Gauge M30x3.5 Precision Tapered Thread Inspection Tool

Product Description

Metric thread ring gauges are precision inspection tools used for checking the thread of outside diameter on screws, bolts and threaded rods,

typically with normal accuracy including 6g, 6h, 7g, 7h, 8g, 8h, etc.

We utilize 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 verification at maximum material limit,

while the NOGO thread ring gauge is machined to a plus tolerance for verification at minimum material limit.

Key Features

Applications

Threaded ring gauges are primarily used to measure thread diameter and pitch, offering high precision, wide measurement range,

and simple operation.They are widely used in machinery manufacturing, aerospace, automotive manufacturing, and other industrial fields.

Usage Precautions

Avoid touching the working surface with bare hands to prevent rust.
Store properly on stable surfaces, not on machine tool holders or guide rails.
Inspect regularly for damage, rust, or deformation.
Clean rust with gasoline soak and apply anti-rust oil when needed.
Do not store working surfaces together to prevent adhesion damage.
Clean thoroughly after use and store in dry conditions.
