Spi 29-711-9 Class Zz Plus Plug Gage 0.711 in

Product Description

The SPI 29-711-9 is a Class ZZ Plus plug gage designed for precision go/no-go inspection of 0.711-inch diameter bores and holes. Manufactured from steel, this gage delivers a tolerance of 0.0002 inches, meeting Class ZZ Plus standards for dimensional verification in production and quality control environments. Machinists, tool and die technicians, and quality inspection professionals use plug gages like this one to confirm that machined holes fall within acceptable tolerance limits quickly and without the setup time required by measuring instruments.

This gage is suited for inspecting drilled, reamed, or bored holes in manufacturing and machine shop settings. It is appropriate for both incoming inspection and in-process quality checks on production runs where 0.711-inch diameter features must be verified. The compact size and light weight of 0.2 pounds make it easy to handle at the machine or inspection bench.

Compatibility

Designed as a standard Class ZZ Plus plug gage for go/no-go inspection of 0.711-inch diameter bores in general machining and quality control applications.

Installation Notes

Plug gages are used by machinists and quality technicians and require no installation. Before use, clean the gage and the bore being inspected to remove chips, coolant, or debris that could affect readings. Handle the gage carefully to avoid dropping or striking it, as impact damage can alter the ground diameter and compromise accuracy. Store the gage in its case or on a protected surface when not in use to prevent corrosion and wear.
