Spi 19-848-1 Class Zz Minus Plug Pin Gage 0.848 in

Product Description

The SPI 19-848-1 is a Class ZZ minus plug pin gage machined from steel for dimensional inspection and go/no-go gauging applications. This gage measures bore diameters at 0.848 inches and holds a tolerance of 0.0002 inches, making it suitable for quality control work where repeatable, accurate hole measurement is required. Class ZZ is the standard tolerance class for general-purpose plug gages used in production and incoming inspection environments. Machinists, toolmakers, and quality technicians use this gage to verify hole size conformance to print specifications.

This plug pin gage is applied in machine shops, fabrication facilities, and manufacturing inspection stations where bore verification is part of standard workflow. It is sized for 0.848-inch diameter holes and fits single-piece or low-volume inspection needs given its individual unit packaging. The steel construction provides durability across repeated use in typical shop environments.

Key Features

• 0.848-inch measurement diameter for precise bore verification
• Class ZZ tolerance class suited for general-purpose production gauging
• Minus designation indicates the gage is ground to the low side of the tolerance band
• 0.0002-inch tolerance for consistent, repeatable dimensional checks
• Steel construction for durability and resistance to wear in shop environments

Compatibility

Designed for use as a general-purpose plug gage for inspecting 0.848-inch diameter bores in production and quality control applications.

Installation Notes

Plug pin gages are handled and used by machinists and quality control technicians. Before use, clean the gage and the bore being inspected to remove chips, oil, and debris that could affect readings. Do not force the gage into a bore; forcing can damage the gage surface and compromise its calibration. Store the gage in a protected case away from other tooling to prevent nicks and wear on the gauging surface.
