Spi 19-462-1 Class Zz Minus Plug Pin Gage 0.462 in

Product Description

The SPI 19-462-1 is a Class ZZ minus plug pin gage manufactured from steel, used to verify hole diameters in precision machining and quality control applications. The gage measures 0.462 inches in diameter with a tolerance of 0.0002 inches, making it suitable for go/no-go inspection workflows where close tolerances must be confirmed. Class ZZ is the standard commercial-grade classification for plug gages, appropriate for general shop-floor inspection. Machinists, tool-and-die technicians, and quality control inspectors use pin gages like this to check bored, drilled, or reamed holes against a specified diameter.

This plug pin gage is used in metalworking, fabrication, and manufacturing environments where hole-diameter verification is part of the production or inspection process. The minus designation means the gage is ground to the low side of the nominal diameter, which is the standard configuration for a go gage in a go/no-go inspection setup. It is suited for both production floor checks and incoming inspection of machined components.

Key Features

• 0.462 inch nominal diameter for precise hole verification
• Class ZZ classification — standard commercial-grade plug gage tolerance
• Minus tolerance ground to 0.0002 inches for consistent go-gage performance
• Steel construction for durability in shop-floor conditions
• Single-piece package suitable for individual replacement or kit supplementation

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in go/no-go inspection setups requiring a 0.462 inch nominal hole diameter check.

Installation Notes

Pin gages are handled and used by machinists and quality control technicians following standard metrology practices. Clean the gage and the hole being checked before use to prevent debris from affecting readings. Do not force the gage into a hole; excessive insertion force can damage the gage surface and compromise measurement accuracy. Store pin gages in a protected case away from moisture to prevent corrosion of the steel surface.
