Spi 19-213-8 Class Zz Minus Plug Pin Gage 0.213 in

Product Description

The SPI 19-213-8 is a Class ZZ minus plug pin gage designed for dimensional inspection and go/no-go gauging applications. This single-ended pin gage checks hole diameters to a nominal size of 0.213 inches with a minus tolerance of 0.0002 inches, confirming that bores meet minimum acceptance criteria. Machined from steel for durability and dimensional stability, this gage is used by machinists, quality control technicians, and tool-room professionals performing precision measurement work on machined components and assemblies.

Class ZZ is the standard tolerance grade for plug pin gages used in general workshop and production inspection environments. This gage is suited for checking drilled, reamed, or bored holes in metal or plastic workpieces where a nominal diameter of 0.213 inches must be verified. It is commonly used on the shop floor, at inspection stations, and in tool rooms as part of a go/no-go gauging process to quickly qualify hole dimensions during or after machining operations.

Key Features

• Nominal diameter of 0.213 inches for targeted bore inspection
• Class ZZ minus tolerance of 0.0002 inches for standard workshop gauging
• Steel construction provides wear resistance and long service life
• Single-piece design for straightforward go/no-go gauging workflow
• Lightweight at 0.2 pounds for easy handling during inspection tasks

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in general production and inspection applications requiring verification of 0.213-inch nominal bore diameters.

Installation Notes

Plug pin gages are handled and used by machinists or quality control personnel — no installation tools or trade license is required. Clean the gage and the bore being checked before use to prevent debris from affecting measurement accuracy. Do not force the gage into a hole; apply light, steady hand pressure only. Store the gage in a protective case away from moisture and temperature extremes to preserve dimensional integrity.
