Starrett 67482 Class Zz Plug Gage Set 190 Pc

Product Description

The STARRETT 67482 is a Class ZZ plug gage set designed for precision hole and slot measurement in machining, fabrication, and inspection applications. The set covers a diameter range of 0.061 to 0.25 inches with a plus-tolerance of 0.0002 inches, making it suitable for verifying tight-tolerance bores, slots, and hole locations. All 190 gages are color coded for fast identification, and each set includes a fully adjustable GO gage handle. The steel construction provides durability and dimensional stability under repeated use. A protective case is included to store and transport the full set safely.

This plug gage set is used in manufacturing inspection, toolroom work, and quality-control environments where small hole sizes must be verified to close tolerances. The range from 0.061 to 0.25 inches makes it particularly useful for gaging slots, finding hole distances, and checking drilled or reamed bores in light to medium production settings. Machinists, metrologists, and quality technicians are the primary users. The color-coded design reduces identification errors during high-volume inspection work.

Installation Notes

Plug gages are installed and used by machinists, toolroom technicians, and quality inspectors; no power source or electrical lockout is required. Store gages in the supplied protective case when not in use to prevent damage and contamination. Clean and lightly oil steel gages periodically to prevent corrosion and maintain measurement accuracy. Do not force a gage into an undersized bore, as this can damage the gage or alter its calibrated dimensions.
