Three Wire Sets are the most accurate and widely used method for measuring the effective diameter of screw threads. They ensure highly reliable results for both metric and inch threads.

Key Features:

• Three precision-matched wires for consistent contact

• Suitable for 60° (Unified & Metric) and 55° (Whitworth) threads

• Available for various thread pitches and diameters

• Hardened and polished for wear resistance

• Supplied in complete sets with calibration data

Technical Details:

• Range: 0.2 mm to 6 mm wire diameters

• Accuracy: ±0.001 mm

• Manufactured as per ISO 3650, BS 919, and ANSI B1.2 standards

• Comes with formula chart for quick reference

Applications:

• Inspection and calibration of thread plug gauges

• Precision engineering, aerospace, and automotive sectors

• Thread metrology and quality assurance labs

Benefits:Provides highly accurate thread measurement, minimizes inspection errors, and supports consistent gauge calibration for long-term reliability.
