Spi 29-584-0 Class Zz Plus Plug Gage 0.584 in

Product Description

The SPI 29-584-0 is a Class ZZ Plus plug gage designed to verify bore and hole diameters to a nominal size of 0.584 inches. Built from steel for durability and dimensional stability, this fixed-limit gage provides a tolerance of 0.0002 inches, making it suitable for inspection tasks where close-tolerance verification is required. Machinists, quality technicians, and tool room personnel use plug gages like this one to perform go/no-go checks or to confirm finished bore dimensions against print specifications. The steel construction resists wear during repeated use in production and inspection environments.

This plug gage is used in machine shops, manufacturing facilities, and quality control departments for verifying drilled, reamed, or bored holes at the 0.584-inch nominal diameter. It is appropriate for inspecting workpieces where a repeatable, traceable measurement standard is needed. Class ZZ Plus gages are commonly selected for general-purpose inspection and tool room use where a balance of accuracy and cost is required.

Key Features

• Nominal measurement diameter of 0.584 inches for fixed-limit bore inspection
• Tolerance of 0.0002 inches for close-tolerance verification
• Steel construction for wear resistance and dimensional stability
• Class ZZ Plus classification suitable for general-purpose and tool room inspection
• Compact and lightweight at 0.2 pounds for easy handling at the inspection station

Compatibility

Designed as a general-purpose fixed-limit plug gage for inspecting bores and holes with a nominal diameter of 0.584 inches in standard machined components.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists. Before use, ensure the gage and workpiece are at the same ambient temperature to avoid thermal expansion errors. Clean the bore and gage contact surfaces thoroughly before each inspection pass. Store the gage in its protective case when not in use to prevent nicks or surface damage that would affect measurement accuracy.
