Spi 29-262-3 Class Zz Plus Plug Gage 0.262 Inch

Product Description

The SPI 29-262-3 is a Class ZZ Plus plug gage designed to verify the inside diameter of precision bores and holes. Built to Class ZZ tolerances with a tolerance of 0.0002 inches, this gage is used to check whether a machined hole falls within specification using a Go/No-Go inspection method. The steel construction ensures dimensional stability during repeated use in shop and inspection environments. Machinists, quality control technicians, and toolroom professionals rely on plug gages like this one for fast, reliable attribute inspection of drilled, reamed, or bored features.

The SPI 29-262-3 is suited for inspecting holes with a nominal diameter of 0.262 inches in manufacturing, machining, and quality assurance applications. It is appropriate for use in both job shop and production inspection environments where dimensional verification of machined components is required. This gage is typically used as part of a Go/No-Go gage set or as a standalone check gage for specific hole sizes.

Installation Notes

Plug gages are handled and used by machinists and quality control technicians. Clean the gage and the bore being inspected before use to prevent debris from affecting the reading or damaging the gage surface. Apply light, even hand pressure when inserting the gage into the bore — do not force or hammer the gage. Store the gage in a protective case away from other metal tools to preserve the lapped surface finish and dimensional accuracy.
