Mitutoyo 64AAA223 Thread Measuring Wire 16 Tpi 3 Piece

Product Description

The MITUTOYO 64AAA223 is a thread pitch diameter measuring wire designed for precise thread measurement in metrology and quality control applications. Engineered for 16 TPI threads with a 0.06 inch pitch, this wire enables accurate pitch diameter readings when used in conjunction with a micrometer. The nominal best wire diameter is 0.03608 inches, and the nominal constant is 0.0563 inches — values that allow technicians to apply the standard three-wire measurement method with confidence. Each set contains 3 wires, each measuring 2.25 inches in length. Machinists, tool and die makers, and quality inspectors rely on these wires for verifiable thread conformance.

These measuring wires are suited for use with thread plug gages in shop-floor inspection and laboratory metrology environments. The three-wire method is a standard practice for determining the pitch diameter of external threads on machined parts, fasteners, and precision components. This set is appropriate wherever 16 TPI thread verification is required, including aerospace, industrial manufacturing, and general precision machining contexts.

Installation Notes

Thread measuring wires are used by machinists and quality control technicians — no power source or shutoff is required. Handle wires carefully to avoid nicks or bends that could affect measurement accuracy. Wires should be cleaned before use and stored in their protective case when not in service. Follow your facility's calibration and measurement procedures to ensure traceable results.
