Wear Resistant Car Testing Tools Screw Plug Gauge No Go Gage For Measuring Hole Groove Width

Sturdy Wear-Resistant High Precision Thread Plug Gauge , Thread Go/NO-Go Gage For Measuring Hole , Groove Width

Features:

Material: The measuring head adopts GR15 bearing steel and has strict heat treatment hardness of 58-65HRC. It is integrally formed and has high hardenability. The hexagonal shank is made of preferably solid steel, threaded structure, convenient link, and the surface is matte and non-slip.

Accuracy: 7H
100% brand new and high quality.
Thread plug gauge is a tool to measure the correctness of internal thread size.
Thread plug gauge under 100mm is taper shank thread plug gauge.
Thread plug gauge 100 mm above is double screw thread plug gauge.
Easy to operate and maintain, supercor performance.

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.
