Spi 29-601-2 Class Zz Plus Plug Gage 0.601 Inch

Product Description

The SPI 29-601-2 is a Class ZZ Plus plug gage used to verify bore and hole dimensions to a nominal diameter of 0.601 inches. It holds a tolerance of 0.0002 inches, making it suitable for go/no-go inspection work where dimensional accuracy is critical. Constructed from steel, this gage is designed for use in machine shops, manufacturing facilities, and quality control environments. Dimensional inspectors, machinists, and quality technicians use Class ZZ plug gages as a standard tool for confirming whether a drilled, reamed, or bored hole meets print specifications.

Class ZZ plug gages are the most common tolerance class for general-purpose inspection of production parts. This gage is appropriate for checking hole diameters in metal, plastic, and composite workpieces where a 0.601-inch nominal bore must be verified. It suits incoming inspection, in-process checks, and final inspection stations in job shop and production environments alike.

Key Features

• Nominal measurement diameter of 0.601 inches for precise bore verification
• Class ZZ Plus tolerance of 0.0002 inches for general-purpose dimensional inspection
• Steel construction provides durability and wear resistance in production environments
• Compact and lightweight at 0.2 pounds for easy bench and floor use
• Single-piece package quantity supports individual technician or toolroom stocking

Compatibility

Designed as a general-purpose Class ZZ Plus plug gage for verifying 0.601-inch nominal bore diameters in standard go/no-go inspection applications across a range of industries and workpiece materials.

Installation Notes

Plug gages are handled and used by dimensional inspectors and machinists following standard metrology practices. Before use, clean both the gage and the workpiece bore with a lint-free cloth to remove chips, oil, and debris that could affect the reading. Do not force the gage into the bore, as forcing can damage the gage surface and produce false readings. Store the gage in a protective case away from other tooling to prevent nicking or corrosion of the precision surface.
