Spi 29-463-7 Class Zz Plus Plug Gage 0.463 Inch

Product Description

The SPI 29-463-7 is a Class ZZ Plus plug gage used to verify bore and hole diameters to a nominal size of 0.463 inches with a tolerance of 0.0002 inches. Plug gages of this class are go/no-go inspection tools used in precision machining, quality control, and production environments. The Class ZZ designation indicates a commercial-grade tolerance tier appropriate for inspection of general-purpose fits. This gage is made from steel for dimensional stability and wear resistance. Machinists, quality technicians, and tool-room professionals rely on this type of gage to confirm that drilled, reamed, or bored holes fall within specified dimensional limits.

This plug gage is suited for use on the shop floor or in inspection departments handling production parts. It is appropriate for any application requiring verification of a 0.463-inch nominal hole diameter, including machined components, fixtures, and assemblies. Typical users include CNC and manual machining operations, quality assurance labs, and tooling departments. The gage is packaged individually and is ready for immediate use in standard go/no-go inspection workflows.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for commercial-grade inspection accuracy
• Steel construction provides dimensional stability and resistance to wear
• Compact and lightweight at 0.2 pounds for easy handling during inspection
• Individual packaging keeps the gage protected and ready for use

Compatibility

Designed as an OEM-style replacement or direct-use plug gage for any application requiring go/no-go inspection of a 0.463-inch nominal bore diameter in standard Class ZZ Plus tolerance workflows.

Installation Notes

Plug gages are handled and used by machinists or quality technicians and do not require installation in the traditional sense. Clean the gage and the bore to be measured before use to prevent debris from affecting readings. Store the gage in its case or protective sleeve when not in use to prevent surface damage. Follow ASME B89.1.5 or your facility gauge-control procedures for calibration intervals and handling standards.
