Spi 29-587-3 Class Zz Plus Plug Gage 0.587 in

Product Description

The SPI 29-587-3 is a Class ZZ Plus plug gage designed to inspect and verify bore diameters of 0.587 inches with a tolerance of 0.0002 inches. Plug gages of this class are used in go/no-go inspection workflows to confirm that machined holes meet dimensional specifications. The steel construction provides durability under repeated use in shop floor conditions. This gage is sized for single-bore inspection and is handled by machinists, quality control technicians, and toolroom personnel in manufacturing and precision machining environments.

Class ZZ Plus plug gages are standard tooling in inspection departments, job shops, and production machining facilities. They are appropriate for checking drilled, reamed, or bored holes in metal, plastic, or composite workpieces. The 0.587-inch diameter designation makes this gage suitable for applications where that bore size is held to close dimensional tolerances. It is typically used as part of a broader gage set or as a standalone check for a specific feature dimension.

Key Features

• Class ZZ Plus accuracy rating for reliable bore diameter inspection
• Nominal measurement diameter of 0.587 inches
• Tolerance of 0.0002 inches for precise dimensional verification
• Steel construction for durability and wear resistance in shop use
• Single-piece design suited for go/no-go inspection procedures

Compatibility

Designed as a standard Class ZZ Plus plug gage for inspection of 0.587-inch nominal bore diameters in machined components across general manufacturing and toolroom applications.

Installation Notes

Plug gages are handled by quality control technicians and machinists and require no power or permanent installation. Clean the gage and the bore before use to remove chips, coolant, or debris that could affect measurement accuracy. Handle with care to avoid dropping or contacting hard surfaces, as impact damage can alter gage dimensions and invalidate its calibration. Gages should be recalibrated periodically per the facility quality management program to ensure continued accuracy.
