Value Collection 600-0500 Thread Measuring Wire 48-3 Tpi

Product Description

The VALUE COLLECTION 600-0500 is a 48-piece thread pitch diameter measuring wire set used to accurately measure thread pitch diameters on threaded fasteners and tapped holes. The set covers 48 to 3 threads per inch (TPI) and 0.5 to 6mm pitch, making it suitable for both unified inch and metric thread forms. Each wire measures 3 inches in length. Machinists, tool-and-die workers, and quality control technicians use these wires in conjunction with a micrometer to perform three-wire thread measurement, a standard method for verifying thread pitch diameter to tight tolerances.

This set is suited for use in machine shops, manufacturing facilities, and precision measurement environments where thread verification is required on both inch-series and metric fasteners. The wide TPI and pitch range means a single set handles the most common thread forms encountered in general machining and inspection work. The 48-piece count provides a wire for each pitch increment across the stated range, reducing the need for multiple separate sets.

Key Features

• Covers 48 to 3 TPI for unified inch thread measurement
• Covers 0.5 to 6mm pitch for metric thread measurement
• Each wire is 3 inches in length for consistent micrometer contact
• 48-piece set spans the full stated TPI and pitch range
• Used with a micrometer for three-wire pitch diameter measurement

Compatibility

Designed for use with standard outside micrometers when performing three-wire thread measurement on unified inch and metric threaded parts across the 48 to 3 TPI and 0.5 to 6mm pitch ranges.

Installation Notes

Thread measuring wires are a precision metrology tool and do not require installation. Handle wires carefully to avoid nicks or surface damage that could affect measurement accuracy. Store wires in their case when not in use to prevent contamination and physical damage. Three-wire measurement should be performed by personnel familiar with the applicable thread standard and micrometer technique.
