Spi 19-567-7 Class Zz Minus Plug Pin Gage 0.567 in

Product Description

The SPI 19-567-7 is a Class ZZ minus plug pin gage used to verify hole diameters in precision machining and quality control applications. It measures 0.567 inches in diameter and is manufactured from steel for durability and dimensional stability. The minus tolerance configuration means the gage is ground to the low end of the tolerance band, a standard practice for go-gage applications where the gage must pass through a conforming hole. With a tolerance of 0.0002 inches, this pin gage meets Class ZZ specifications for general-purpose inspection work. Machinists, tool and die technicians, and quality inspectors use plug pin gages like this one to confirm that drilled, reamed, or bored holes fall within acceptable dimensional limits.

This pin gage is suited for use in machine shops, manufacturing facilities, and inspection departments where hole diameter verification is part of the production or quality assurance workflow. It is appropriate for use on ferrous and non-ferrous workpieces wherever a 0.567-inch nominal hole diameter must be checked. Class ZZ gages are widely used for in-process and final inspection in general-purpose industrial applications.

Key Features

• 0.567-inch diameter for direct hole verification at that nominal size
• Class ZZ minus tolerance ground to 0.0002 inches for general-purpose inspection
• Steel construction provides wear resistance and dimensional stability
• Minus configuration positions the gage at the low end of the tolerance band, standard for go-gage use
• Single-piece package quantity suits individual inspection or replacement needs

Compatibility

Designed as a general-purpose Class ZZ minus plug pin gage for use in standard inspection and quality control setups requiring verification of a 0.567-inch nominal hole diameter.

Installation Notes

Plug pin gages are handled and stored carefully to avoid surface damage that would affect measurement accuracy. Clean the gage and the hole being checked before use to remove chips, coolant, or debris. Apply light gage oil when checking ferrous materials to prevent corrosion and reduce wear. Do not force the gage through an undersized hole, as this can damage the gage surface and compromise calibration.
