Spi 29-732-5 Class Zz Plus Plug Gage 0.732 Inch

Product Description

The SPI 29-732-5 is a Class ZZ Plus plug gage designed for go/no-go dimensional inspection of bored holes and machined openings with a nominal diameter of 0.732 inches. Built to Class ZZ Plus tolerances of 0.0002 inches, this gage provides a reliable reference for verifying hole size conformance on the shop floor or in a quality-control environment. The steel construction delivers the rigidity and wear resistance required for repeated use in production inspection workflows. Machinists, quality technicians, and toolroom professionals use plug gages like this one to confirm that finished bores fall within specified dimensional limits before assemblies move to the next stage.

This plug gage is suited for light industrial and precision manufacturing applications where hole diameter verification is part of standard inspection protocol. It is appropriate for use on machined components in metal fabrication, mechanical assembly, and toolroom operations. The 0.732-inch measurement diameter covers a common bore size encountered in shaft-fit and fastener-clearance applications. Single-unit packaging makes it practical for individual purchase by a technician outfitting a personal gage set or replacing a worn or damaged gage in an existing kit.

Key Features

• Class ZZ Plus tolerance rating of 0.0002 inches for reliable go/no-go inspection
• 0.732-inch nominal measurement diameter for common bore-size verification
• Steel construction provides durability and resistance to wear during repeated use
• Compact and lightweight at 0.2 pounds for easy handling and storage
• Single-unit packaging with a minimum order quantity of 1

Compatibility

Designed as an OEM-style Class ZZ Plus plug gage for general-purpose bore inspection on machined components requiring a 0.732-inch nominal hole diameter check.

Installation Notes

Plug gages are used by quality technicians and machinists and require no installation in the traditional sense, but proper handling is essential for accurate results. Clean both the gage and the bore thoroughly before use to remove chips, coolant, and debris that could affect measurement. Do not force the gage through an undersize bore, as this will damage the gage surface and compromise its calibration. Store the gage in a protective case away from abrasive materials to maintain its tolerance class over time.
