Spi 19-603-0 Class Zz Minus Plug Pin Gage 0.603 in

Product Description

The SPI 19-603-0 is a Class ZZ minus plug pin gage machined from steel, designed to check the minimum acceptance limit of a hole or bore measuring 0.603 inches in diameter. With a tolerance of 0.0002 inches, it delivers the precision required for go/no-go inspection in production and quality control environments. Class ZZ is the standard tolerance grade for workshop-grade plug gages used in general dimensional inspection. This gage is handled by machinists, quality technicians, and tool-and-die professionals who need reliable, repeatable measurement confirmation during part verification.

This plug pin gage is suited for use in machine shops, manufacturing facilities, and inspection departments where bore diameter acceptance must be confirmed to tight tolerances. It is applied in scenarios where a minus gage member is needed to verify that a hole has not been machined undersize. The single-end design at 0.603 inches makes it a direct-use tool for any inspection station working with that nominal bore dimension.

Key Features

• Class ZZ tolerance grade for general workshop and production inspection use
• Minus gage member confirms minimum acceptable bore diameter at 0.603 inches
• Tolerance of 0.0002 inches for precise go/no-go dimensional verification
• Steel construction for durability and dimensional stability under repeated use
• Compact and lightweight at 0.2 pounds for easy bench or hand use

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use with 0.603-inch nominal bore diameter inspection applications in general machining and quality control environments.

Installation Notes

Plug pin gages are handled by quality technicians and machinists and require no permanent installation. Before use, clean both the gage and the bore to be checked to remove chips, coolant, or debris that could affect measurement accuracy. Do not force the gage into a bore; excessive insertion force can damage the gage member or the workpiece. Store the gage in a protected case and apply a light coat of oil when not in use to prevent corrosion.
