Spi 19-602-2 Class Zz Minus Plug Pin Gage 0.602 in

Product Description

The SPI 19-602-2 is a Class ZZ minus plug pin gage with a nominal diameter of 0.602 inches and a tolerance of 0.0002 inches. It is manufactured from steel for durability and consistent dimensional accuracy across repeated measurements. Plug pin gages are go/no-go inspection tools used to verify bore diameters, hole sizes, and internal dimensions on machined parts. This minus-tolerance gage falls within the Class ZZ specification, the most commonly used gage class for general shop-floor and inspection applications. Machinists, quality technicians, and tool-and-die professionals rely on these gages for part acceptance and process control.

This gage is suited for use in manufacturing, fabrication, and machine shop environments where precise hole diameter verification is required. It is appropriate for inspection of drilled, reamed, or bored holes on production parts and assemblies. Class ZZ gages are typically applied in general-purpose inspection work rather than high-precision laboratory settings, making this gage a practical choice for in-process quality checks on the shop floor.

Key Features

• Nominal diameter of 0.602 inches for direct hole-size verification
• Class ZZ minus tolerance of 0.0002 inches for general-purpose inspection accuracy
• Steel construction provides wear resistance and dimensional stability
• Minus designation means the gage is ground to the low side of tolerance, supporting standard go-gage applications
• Compact, single-piece pin gage format for quick manual inspection

Compatibility

Designed as a general-purpose Class ZZ minus plug pin gage suitable for verifying 0.602-inch nominal bore diameters on machined components across a wide range of manufacturing and inspection applications.

Installation Notes

Plug pin gages are used by quality technicians and machinists and require no installation. Clean the gage and the bore being checked before use to prevent debris from affecting measurement results. Handle pin gages carefully to avoid drops or impacts that can alter the ground diameter. Store gages in a protective case when not in use to preserve accuracy and surface finish.
