Spi 19-576-8 Class Zz Minus Plug Pin Gage 0.576 in

Product Description

The SPI 19-576-8 is a Class ZZ minus plug pin gage used to verify bore and hole diameters in precision machining and inspection applications. The gage measures 0.576 inches in diameter and is manufactured from steel for durability and dimensional stability. With a tolerance of 0.0002 inches, it conforms to Class ZZ specifications, which are the standard for general-purpose shop-floor inspection work. Machinists, quality control technicians, and tool room personnel use pin gages like this to confirm whether a hole or bore is within acceptable dimensional limits before parts move to the next stage of production.

This plug pin gage is suited for use in manufacturing environments where hole size verification is part of the standard inspection process. It is appropriate for checking drilled, reamed, or bored holes in metal, plastic, or composite workpieces. The minus designation indicates the gage is made to the lower tolerance limit, which is the standard for go/no-go inspection setups used across general machining and fabrication shops.

Key Features

• Class ZZ tolerance class rated for general-purpose shop inspection use
• Minus designation conforms to lower tolerance limit for go/no-go applications
• 0.0002 inch tolerance for reliable dimensional verification
• Steel construction provides dimensional stability and resistance to wear
• 0.576 inch diameter for direct bore and hole measurement

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use with pin gage handles and sets in general-purpose dimensional inspection applications.

Installation Notes

Pin gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Before use, clean the gage and the bore being checked with a lint-free cloth to remove debris that could affect readings. Store the gage in a protective case away from other metal tools to prevent nicks or surface damage that would compromise measurement accuracy. Do not force the gage into an undersized bore.
