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:
The hexalobular internal driving feature shall allow the go gauge to enter freely to the penetration depth,t, as specified in the relevant product standards. The no go gauges shall not enter the hexalobular internal driving feature to a depth greater than the fallaway allowance specified
✅ 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.
