Spi 19-701-2 Class Zz Minus Plug Pin Gage 0.701 in

Product Description

The SPI 19-701-2 is a Class ZZ minus plug pin gage designed for go/no-go inspection and hole diameter verification in precision manufacturing and quality control environments. With a nominal diameter of 0.701 inches and a minus tolerance of 0.0002 inches, this gage provides accurate, repeatable measurements suited to production-floor and inspection-bench use. Constructed from steel, the 19-701-2 is built to withstand routine handling in shop environments. It is used by machinists, quality technicians, and tool-room professionals who need a reliable, traceable reference for bore and hole acceptance checks.

This plug pin gage is applicable in metal fabrication shops, machine shops, and quality inspection departments where hole size conformance is critical. It is well suited for checking drilled, reamed, or bored holes in production parts. The Class ZZ designation indicates this gage meets standard commercial-grade tolerance requirements, making it appropriate for general inspection work where high-volume checking is the primary need rather than master-gage or inspection-grade precision.

Key Features

• Nominal diameter of 0.701 inches for direct hole size verification
• Class ZZ minus tolerance of 0.0002 inches for consistent commercial-grade accuracy
• Steel construction for durability under repeated shop-floor use
• Compact and lightweight at 0.2 pounds for easy single-hand operation
• Go/no-go inspection format speeds up production acceptance checks

Compatibility

Designed as a commercial-grade plug pin gage for use in standard go/no-go inspection applications requiring a 0.701-inch nominal bore diameter check.

Installation Notes

Plug pin gages are handled by machinists and quality technicians and require no installation in the traditional sense. Clean both the gage and the bore before use to prevent debris from affecting readings or causing surface damage. Do not force the gage into an undersize hole, as this can damage the gage surface and compromise measurement integrity. Store the gage in a protective case away from moisture and temperature extremes to maintain dimensional stability.
