Spi 19-596-6 Class Zz Minus Plug Pin Gage 0.596 in

Product Description

The SPI 19-596-6 is a Class ZZ minus plug pin gage designed for go/no-go dimensional inspection of machined holes and bores. It measures a nominal diameter of 0.596 inches with a minus tolerance of 0.0002 inches, placing it within Class ZZ specification for general inspection and shop-floor quality control work. Constructed from steel, this pin gage provides the hardness and wear resistance needed for repetitive gauging operations. Machinists, quality control technicians, and tool-room professionals use this type of gage to verify hole diameter compliance during production runs or incoming inspection.

This pin gage is suited for use in manufacturing environments, machine shops, and inspection departments where precise bore measurement is required. The 0.596-inch nominal diameter makes it applicable to checking drilled, reamed, or bored holes to close dimensional tolerances. Class ZZ gages are commonly used for production gauging where tolerance requirements are less stringent than Class Z or ZZ-plus applications. The gage is sold individually and is compatible with standard pin gage handle sets for convenient handheld use.

Key Features

• Class ZZ minus tolerance classification for production-level hole gauging
• Nominal diameter of 0.596 inches with a minus tolerance of 0.0002 inches
• Steel construction for durability and wear resistance in shop environments
• Compact and lightweight at 0.2 pounds for easy single-hand operation
• Sold as a single unit, compatible with standard pin gage handle sets

Compatibility

Designed as an OEM-style replacement or direct-use pin gage for standard pin gage handle sets used in general machining and inspection applications requiring a 0.596-inch nominal diameter Class ZZ minus plug gage.

Installation Notes

Pin gages are installed and used by machinists and quality technicians during inspection procedures. Before use, clean the gage and the bore being checked to remove chips, coolant, and debris that could affect measurement accuracy. Insert the gage gently into the bore without forcing it, as Class ZZ gages are precision instruments and can be damaged by excessive lateral load. Store the gage properly in a protective case or roll when not in use to prevent surface damage that would affect tolerance accuracy.
