Spi 19-752-5 Class Zz Minus Plug Pin Gage 0.752 in

Product Description

The SPI 19-752-5 is a Class ZZ minus plug pin gage used to verify hole diameters in precision machining and inspection work. It measures a nominal diameter of 0.752 inches with a minus tolerance of 0.000200 inches, meeting Class ZZ accuracy standards for go/no-go gauging applications. Constructed from steel for durability and dimensional stability, this gage is a standard tool in quality control environments where consistent bore verification is required. Machinists, toolmakers, and quality technicians use plug pin gages like this one during in-process inspection and final part acceptance checks.

This gage is suited for use in machine shops, fabrication facilities, and metrology labs where hole diameter conformance must be confirmed to close tolerances. It is appropriate for both production floor inspection and bench-level quality control work. The 0.752-inch diameter range covers a common bore size found in general mechanical components, fixtures, and assemblies. This is a single-gage unit intended for individual diameter verification rather than set-based gauging.

Key Features

• Nominal diameter of 0.752 inches for direct bore verification at that dimension
• Class ZZ minus tolerance of 0.000200 inches for standard-grade inspection accuracy
• Steel construction provides wear resistance and dimensional stability during repeated use
• Compact and lightweight at 0.2 pounds for easy handling during inspection tasks
• Single-piece unit ships individually, ready for immediate use

Compatibility

Designed as a standard Class ZZ plug pin gage for verifying 0.752-inch nominal bore diameters in general machining and inspection applications.

Installation Notes

Plug pin gages are used by machinists and quality control technicians — no special installation is required. Clean the gage and the bore being checked before use to prevent debris from affecting the reading. Store the gage in a protective case away from temperature extremes to maintain dimensional accuracy. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece.
