Customizable 7H Thread Plug Gauge GO And No GO Non-Standard Tap & Die Measuring Tools

Specification:
Material: Bearing steel
Weight: 14~221g/0.5~7.8oz
Inspection and measurement process
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.

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.
