Spi 616-82902 Class Zz Plug Gage Set 90 Pc 0.011-0.1 in

Product Description

The SPI 616-82902 is a 90-piece Class ZZ double-end plug gage set covering a measurement range of 0.011 to 0.1 inches. Each gage in the set is manufactured from steel and held to a plus tolerance of 0.0005 inches, consistent with Class ZZ go/no-go inspection standards. Double-end construction places both the go and no-go members on opposite ends of a single handle, reducing the number of individual tools needed at the bench. This set is used by machinists, quality control technicians, and tool room personnel to verify bore and hole diameters to tight dimensional specifications.

This plug gage set is suited for incoming inspection, in-process quality checks, and final part verification in machine shops, manufacturing facilities, and tool rooms. The 90-piece range provides coverage across small-bore applications from 0.011 to 0.1 inches, making it a practical reference set for shops that work with a broad variety of drilled, reamed, or otherwise finished holes. Steel construction ensures durability under repeated use in production environments.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no installation in the traditional sense applies. Store gages in the provided case to prevent damage to precision ground surfaces. Clean contact surfaces before use and keep gages free of chips, coolant residue, and oils that could affect dimensional accuracy. Do not force a gage into a bore; a go member should pass with light hand pressure only.
