Spi 29-926-3 Class Zz Plus Plug Gage 0.926 in

Product Description

The SPI 29-926-3 is a Class ZZ Plus plug gage designed for precision hole measurement in manufacturing and quality control environments. It measures a nominal diameter of 0.926 inches with a tolerance of 0.0002 inches, making it suitable for go/no-go inspection workflows where tight dimensional control is required. Constructed from steel for durability and dimensional stability, this gage is a standard tool for machinists, toolroom technicians, and quality assurance personnel who need reliable, repeatable hole verification on the shop floor.

This plug gage is used in machine shops, production facilities, and inspection departments to verify bore diameters in workpieces. Class ZZ is the standard tolerance class for general-purpose inspection gaging, appropriate for checking holes in manufactured components where dimensional accuracy is critical. It is typically used as part of a go/no-go gage set or as a standalone check gage for in-process or final inspection.

Compatibility

Designed as a general-purpose Class ZZ Plus plug gage for inspecting bored holes with a nominal diameter of 0.926 inches in standard manufacturing and quality control applications.

Installation Notes

Plug gages are handled and used by machinists and quality control technicians following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain accuracy. Do not force the gage into a bore; apply only light, consistent hand pressure to avoid wear or measurement error. Store in a protective case away from temperature extremes to preserve dimensional calibration.
