Spi 19-460-5 Class Zz Minus Plug Pin Gage 0.46 in

Product Description

The SPI 19-460-5 is a Class ZZ minus plug pin gage used to verify hole diameters and bore tolerances in precision machining and quality control applications. It measures 0.46 inches in diameter and holds a tolerance of 0.0002 inches, making it suitable for go/no-go inspection work where tight dimensional control is required. Constructed from steel for durability and wear resistance, this pin gage is a standard tool in inspection departments, machine shops, and manufacturing environments. Licensed metrology technicians, machinists, and quality control inspectors are the primary users of this type of gage.

This pin gage is used in settings where hole size verification is part of the production or incoming inspection process. It is well suited for checking drilled, reamed, or bored holes in metal components. The minus designation indicates the gage is manufactured to the lower end of the tolerance band, consistent with Class ZZ specifications for go gages. Typical applications include general-purpose dimensional inspection in job shops, production facilities, and tool rooms.

Key Features

• 0.46 inch diameter for direct hole size verification
• Class ZZ tolerance classification for general-purpose inspection use
• Minus tolerance designation for go-gage applications
• 0.0002 inch tolerance for precise dimensional control
• Steel construction for durability in shop environments

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in general-purpose dimensional inspection of 0.46 inch diameter holes in machined components.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store the gage in its protective sleeve or case when not in use to avoid surface damage. Apply a light coat of instrument-grade oil before storage if the gage will not be used for an extended period. Calibration should be verified against a traceable standard before use in critical inspection applications.
