Spi 19-608-9 Class Zz Minus Plug Pin Gage 0.608 in

Product Description

The SPI 19-608-9 is a Class ZZ minus plug pin gage designed to verify bore diameters and hole sizes in precision measurement and quality control applications. With a nominal diameter of 0.608 inches and a tolerance of 0.0002 inches, this gage provides accurate go/no-go verification for machined components. Constructed from steel for durability and dimensional stability, it is used by machinists, quality technicians, and tool and die professionals who require reliable inspection of tight-tolerance bored features.

This plug pin gage is suited for use in machine shops, manufacturing facilities, and inspection departments where hole diameter conformance must be confirmed before parts move to assembly or shipment. Class ZZ gages are the most widely used class for general-purpose inspection of holes produced by drilling, reaming, or boring operations. The minus designation indicates the gage is ground undersized relative to the nominal diameter, making it appropriate for go-gage applications.

Key Features

• Nominal diameter of 0.608 inches for precise hole verification
• Class ZZ tolerance rating for general-purpose inspection use
• Minus designation — ground undersized for go-gage fitment
• Tolerance of 0.0002 inches ensures repeatable measurement accuracy
• Steel construction for long service life and dimensional stability

Compatibility

Designed as an OEM-style replacement or standard inspection tool for use with handle sets and gage holders that accept pin gages in the 0.608-inch nominal diameter range. Confirm handle compatibility with your existing gage set before installation.

Installation Notes

Pin gages are installed by pressing or threading the gage wire into a compatible handle per the manufacturer instructions for that handle system. Clean both the gage and the bore to be inspected before use to prevent false readings from debris or oil contamination. Do not force the gage into an undersized hole, as this can damage the gage surface and compromise measurement accuracy. Inspection should be performed by or under the supervision of a qualified quality control technician.
