NOGO Type M30X1.5-7H Metric Thread Plug Gauge for Testing Tapped Holes
These metric plug ring gauges are precision metrology tools designed for checking threaded or tapped holes. They verify proper thread type, major diameter, minor diameter, pitch diameter, and pitch against mating thread gauges.
Manufactured using first-grade thread machining centers and measuring equipment, our plug gauges deliver high precision for global customers. Their simple working principle allows for quick results and easy operator training.
For small threaded parts, the gauge features a double-ended design with GO gauge on one end and NOGO on the other. Larger parts may use separate pieces. Acceptance criteria:
- GO gauge must pass through entire length without excessive rotational force
- NOGO gauge may enter no more than 2 turns when checked at both ends
Available in GO thread plug gauges, NOGO thread plug gauges, and combination GO/NOGO types.
- Metric thread plug gauge
- Accuracy options: 5g,5h, 6g,6h,7g,7h, etc.
- Available in GO, NO GO, and combination GO/NOGO types
- Conforms to DIN13 standard
- Wear and corrosion resistant with stable structure
- Includes fitted case

Thread plug gauges are essential for inspecting thread size compliance, widely used in:
- Automobile manufacturing
- Aerospace
- Machining
- Electronic processing
They improve thread accuracy and ensure product qualification rates for both standard and non-standard thread products.
- Avoid touching working surfaces to prevent rust
- Store on stable surfaces (tool cabinet, wooden backing plate) - never on machine tool holders or guide rails
- Regularly inspect for damage, rust, or deformation
- For rust treatment: soak in gasoline, wipe carefully, and apply anti-rust oil
- Never store working surfaces together to prevent adhesion damage
- Clean and store in dry conditions after use
