Spi 29-796-0 Class Zz Plus Plug Gage 0.796 in Dia

Product Description

The SPI 29-796-0 is a Class ZZ Plus plug gage used to verify the inside diameter of machined holes and bores to a precise measurement standard. It measures a nominal diameter of 0.796 inches with a tolerance of 0.0002 inches, making it suitable for go/no-go inspection work in production and maintenance environments. Constructed from steel for durability and dimensional stability, this gage is a standard tool for machinists, toolmakers, and quality control technicians who need reliable, repeatable bore verification.

This plug gage is applied in machine shops, maintenance facilities, and manufacturing inspection stations where inside diameter conformance must be confirmed to close tolerances. It is used on drilled, reamed, or bored holes where dimensional accuracy is critical to component fit and function. The Class ZZ Plus designation indicates it meets accepted standards for working gages used in general production inspection.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Before use, clean both the gage and the bore being inspected to remove chips, oil, or debris that could affect the reading. Store the gage in its protective case when not in use to preserve dimensional accuracy and surface finish.
