Starrett 67483 Class Zz Plug Gage Set 190 Pc Steel

Product Description

The STARRETT 67483 is a Class ZZ plug gage set designed for precision hole and slot measurement in production and inspection environments. The set covers a diameter range of 0.061 to 0.25 inches across 190 individual gages, with a minus-tolerance of 0.0002 inches (0.0002 mm) per Class ZZ specification. Each gage is color coded for fast identification, and a fully adjustable NO-GO gage handle is furnished with the set. Constructed from steel, this set is built for repeated use in demanding shop-floor conditions. Licensed machinists, quality control technicians, and tool-room professionals rely on this type of set for go/no-go verification of tight-tolerance bores and slots.

This plug gage set is suited for inspecting small hole sizes, gaging slots, and determining hole distances in both production and toolroom settings. The 190-piece range provides continuous diameter coverage from 0.061 to 0.25 inches, making it practical for a wide variety of workpieces encountered in general metalworking, mold-and-die, and precision machining applications. The included adjustable NO-GO handle reduces the need for separate handle purchases across the range. Color coding accelerates gage selection during high-volume inspection work.

Installation Notes

Plug gages should be handled and stored by quality control technicians or machinists trained in precision measurement practices. Clean and inspect each gage for burrs or surface damage before use, and store gages in the provided case to prevent wear and corrosion. Do not force a gage through an undersized hole, as this can damage the gage land or alter the calibrated tolerance. Periodic recalibration against certified masters is recommended to maintain measurement traceability per applicable metrology standards.
