Spi 29-232-6 Class Zz Plus Plug Gage 0.232 Inch

Product Description

The SPI 29-232-6 is a Class ZZ Plus plug gage designed for precision hole and bore measurement in manufacturing and quality-control environments. It measures a nominal diameter of 0.232 inches with a tolerance of 0.0002 inches, making it suited for applications where tight dimensional verification is required. The gage is constructed from steel for durability and dimensional stability under repeated use. Machinists, toolmakers, and quality technicians use plug gages like this to perform go/no-go or attribute inspection of drilled, reamed, or bored holes on production floors and in inspection labs.

This gage is applied in metal fabrication shops, machine shops, and precision manufacturing facilities where hole diameter conformance must be verified against engineering tolerances. It is appropriate for both incoming inspection and in-process quality checks on ferrous and non-ferrous workpieces. The 0.232-inch diameter addresses common drill and reamer sizes found in standard inch-series manufacturing processes. At a package quantity of one, it fits single-gage procurement for toolroom or inspection department needs.

Key Features

• Class ZZ Plus tolerance classification for plug gage accuracy
• 0.232-inch nominal measurement diameter
• 0.0002-inch tolerance for tight dimensional verification
• Steel construction for wear resistance and long service life
• Single-piece packaging suits individual toolroom or bench use

Compatibility

Designed as a standard inch-series plug gage for use in go/no-go attribute inspection of holes and bores nominally sized at 0.232 inches in manufacturing and quality-control applications.

Installation Notes

Plug gages are used by toolmakers, machinists, and quality technicians and require no installation in the traditional sense. Before use, clean the gage and workpiece bore to remove chips, coolant, and debris that could affect measurement accuracy. Handle the gage carefully to avoid dropping or nicking the measuring surface, as surface damage will compromise tolerance integrity. Store the gage in its case or designated holder when not in use to prevent corrosion and wear.
