Spi 29-562-6 Class Zz Plus Plug Gage 0.562 Inch

Product Description

The SPI 29-562-6 is a Class ZZ Plus plug gage used to verify the inside diameter of machined holes and bored features to a high degree of accuracy. Built from steel, this go/no-go style measurement tool checks whether a hole falls within tolerance during production or inspection workflows. With a nominal measurement diameter of 0.562 inches and a tolerance of 0.0002 inches, it meets the precision requirements of dimensional inspection tasks common in machining, manufacturing, and quality control environments. Machinists, toolroom technicians, and QC inspectors are the primary users of this type of gage.

This plug gage is suited for use on the shop floor or in the inspection room wherever hole size verification is required. It is appropriate for checking bored, drilled, or reamed holes in metal components where tight tolerances are specified. The 0.562-inch diameter makes it a direct fit for inspection of that specific hole size without the need for adjustable or electronic alternatives.

Key Features

• Class ZZ Plus tolerance classification for dimensional hole inspection
• Nominal measurement diameter of 0.562 inches
• Tolerance of 0.0002 inches for high-precision verification
• Steel construction for durability in production and inspection environments
• Compact and lightweight at 0.2 pounds for easy handheld use

Compatibility

Designed as an OEM-style fixed plug gage for dimensional inspection of 0.562-inch diameter holes in machined metal components and assemblies.

Installation Notes

Plug gages are handled and used by machinists or quality control technicians rather than installed as system components. Before use, clean the gage and the hole being checked to remove chips, coolant, and debris that could affect the reading. Do not force the gage into a hole; forcing can damage both the gage and the workpiece. Store the gage in its case and handle it with care to protect the precision-ground surfaces from wear and corrosion.
