Spi 29-114-6 Class Zz Plus Plug Gage 0.114 in

Product Description

The SPI 29-114-6 is a Class ZZ Plus plug gage used to verify the diameter of machined holes to a high degree of accuracy. The gage measures a nominal diameter of 0.114 inches with a tolerance of 0.0002 inches, making it suitable for precision quality-control applications in manufacturing, machining, and inspection environments. Constructed from steel, it is built to withstand repeated use in shop-floor conditions. Machinists, toolmakers, and quality-control inspectors use plug gages like this one as part of standard go/no-go or dimensional verification routines.

This plug gage is suited for small-diameter bore inspection tasks in precision manufacturing settings. It is used to confirm that drilled, reamed, or bored holes fall within specified dimensional tolerances before parts advance through the production process. Its compact size and steel construction make it practical for bench inspection or inline use on a machining center.

Key Features

• Class ZZ Plus accuracy rating for precision dimensional inspection
• 0.114-inch nominal measurement diameter
• 0.0002-inch tolerance for tight-tolerance bore verification
• Steel construction for durability in production environments
• Compact form factor suited for small-bore applications

Compatibility

Designed for use in standard plug gage applications requiring a 0.114-inch nominal bore diameter check. No specific system or equipment compatibility data was provided by the manufacturer for this part.

Installation Notes

Plug gages are handled by machinists, toolmakers, or quality-control inspectors and do not require power or mechanical installation. Store the gage in its protective case when not in use to prevent damage to the precision-ground surfaces. Clean contact surfaces before use to avoid measurement errors caused by debris or oil buildup. Follow your facility's gage calibration and handling procedures to maintain accuracy over time.
