Spi 19-466-2 Class Zz Minus Plug Pin Gage 0.466 in

Product Description

The SPI 19-466-2 is a Class ZZ minus plug pin gage used to check and verify hole diameters in machined parts and assemblies. Manufactured from steel, this pin gage measures a nominal diameter of 0.466 inches with a minus tolerance of 0.0002 inches, placing it within the Class ZZ specification for general-purpose go/no-go inspection work. Machinists, quality control technicians, and tooling specialists use pin gages like this one to confirm bore dimensions are within drawing tolerance before parts advance in the production process.

Class ZZ plug pin gages are suited for production floor and inspection room use where moderate-precision hole verification is required. The 19-466-2 is appropriate for checking drilled, reamed, or bored holes in ferrous and non-ferrous workpieces. It is a standard tool in job shops, manufacturing facilities, and maintenance shops that require reliable, repeatable dimensional verification without the cost of higher-class precision instruments.

Key Features

• Class ZZ minus tolerance rating for general-purpose hole inspection
• Nominal diameter of 0.466 inches for precise bore verification
• Tolerance of 0.0002 inches (0.0002 mm) for consistent measurement repeatability
• Steel construction for durability in shop environments
• Compact, single-unit form factor for easy handling and storage

Compatibility

Designed as a standard Class ZZ minus plug pin gage for general-purpose dimensional inspection of holes nominally sized at 0.466 inches in diameter across a range of machined components and materials.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, inspect the gage surface for nicks or wear that could affect measurement accuracy. Insert the gage into the bore with light, even hand pressure only — never force a pin gage, as this can damage both the gage and the workpiece. Store in a protective case away from abrasive materials when not in use.
