7H Thread Plug Gauge GO And No GO Gauge Screw Thread Gauge Customizable
 

Inspection and measurement process
 

1. First, clean sheets and impurities must be cleaned before the thread plug gauge and the measured thread are positive, then the thumb and forefinger rotate the ring gauge, so that the thread in the free state can be determined according to the full length of the thread, otherwise it will not be able to determine.
2. After the use of the relevant inspection and metrological institutions inspection and metrology qualified, then the screw plug gauge and the measured thread pair after, use the thumb finger and the index finger rotation ring gauge, screw thread length within 2 pitch to be qualified, otherwise be judged to be non-conforming product.

Principle:
 

✅ Rapid Inspection

• Go End: Acceptable parts must pass smoothly.

• No-Go End: Acceptable parts must not pass, ensuring dimensions stay within tolerance.

✅ Precision & Durability

• Material: High-hardness tool steel (e.g., SKD11) or tungsten carbide, offering wear and corrosion resistance.

• Tolerance: ±0.001–0.005mm (higher precision available upon request).

✅ Versatile Designs

• Supports thread inspection (Thread Gauge), hole diameter checks (Plug Gauge), shaft diameter verification (Snap Gauge), and more.

• Custom non-standard sizes available for complex workpieces.

✅ Compliant with International Standards

• Manufactured per ISO 1502 (threads), ASME B89.1.5 (limit gauges), and other industry standards.

• Applications

• Production Line QC: High-speed screening of batch parts.

• Incoming Inspection (IQC): Supplier material acceptance.

• Mold Debugging: Validating machining dimensions.
