Spi 29-942-0 Class Zz Plus Plug Gage 0.942 in Dia

Product Description

The SPI 29-942-0 is a Class ZZ Plus plug gage designed to verify bore and hole diameters to a nominal measurement of 0.942 inches. It is used to confirm whether an internal diameter is within a specified tolerance, making it an essential tool for dimensional inspection in manufacturing, machining, and quality control environments. Built from steel, this gage delivers the rigidity and wear resistance required for repeated use in production and inspection settings. The tolerance on this gage is 0.0002 inches, which meets Class ZZ Plus standards for go and no-go inspection work.

This plug gage is suited for use in machine shops, fabrication facilities, and industrial inspection departments where hole diameter conformance must be verified to tight tolerances. It is a standard tool for machinists, quality technicians, and metrology professionals working with precision-machined components. The 0.942-inch nominal diameter makes it appropriate for applications involving drilled, reamed, or bored holes in that size range. Single-piece packaging makes it straightforward to integrate into an existing gage inventory.

Compatibility

Designed as a standard Class ZZ Plus plug gage for use in general dimensional inspection of internal bore diameters measuring 0.942 inches nominal.

Installation Notes

Plug gages are handled by quality technicians and machinists during dimensional inspection; no power source is required. Before use, clean the gage and the bore being measured to remove chips, coolant, or debris that could affect accuracy. Handle steel gages with care to avoid drops or impacts that may alter the gage surface or diameter. Store in a protected case or designated gage block when not in use to prevent damage and maintain calibration integrity.
