Spi 29-195-5 Class Zz Plus Plug Gage 0.195 in Dia

Product Description

The SPI 29-195-5 is a Class ZZ Plus plug gage used to verify hole diameters to a tolerance of 0.0002 inches. It measures a nominal diameter of 0.195 inches, making it suited for precision inspection work in machining, fabrication, and quality control environments. The steel construction provides the durability and dimensional stability required for repeated use in production settings. Machinists, quality technicians, and toolroom professionals rely on this type of gage to confirm that drilled, reamed, or bored holes fall within specified limits before parts advance to assembly.

This plug gage is appropriate for use in light manufacturing, job shop, and production inspection applications where hole diameter verification is required at the 0.195-inch nominal size. It is well suited for go/no-go inspection routines on small-diameter holes in metal or plastic workpieces. The compact size and steel construction make it practical for both bench inspection and floor use.

• Compact form factor suited for bench and production floor use

Compatibility

Designed as an OEM-style replacement or direct-use plug gage for inspection applications requiring a 0.195-inch nominal diameter Class ZZ Plus go/no-go gage.

Installation Notes

Plug gages are handled and used by quality technicians and machinists during inspection procedures. Before use, clean the gage and the hole being measured to remove chips, coolant, or debris that could affect readings. Do not force the gage into an undersized hole, as this can damage the gage surface and affect calibration. Store the gage in a protective case or sleeve when not in use to prevent nicks and corrosion.
