Spi 19-862-2 Class Zz Minus Plug Pin Gage 0.862 in

Product Description

The SPI 19-862-2 is a Class ZZ minus plug pin gage designed for dimensional inspection and go/no-go gauging applications. Measuring 0.862 inches in diameter with a minus tolerance of 0.0002 inches, this gage allows machinists and quality control technicians to verify bore and hole dimensions to tight tolerances. The steel construction provides durability and resistance to wear during repeated use. It is a standard single-ended plug gage used in production environments, inspection rooms, and machine shops where precise hole diameter verification is required.

This plug pin gage is suited for use in manufacturing, machining, and quality assurance settings where hole tolerance verification is a routine part of the inspection process. Class ZZ designation indicates a commercial-grade gage appropriate for general-purpose inspection work. It is typically used by machinists, toolmakers, and QC inspectors working with ferrous and non-ferrous components that require controlled bore sizing.

Key Features

• 0.862 inch nominal diameter for direct bore inspection at that dimension
• Class ZZ minus tolerance of 0.0002 inches for commercial-grade go/no-go gauging
• Steel construction for wear resistance and dimensional stability
• Single-piece design suited for production and inspection room use
• Lightweight at 0.2 pounds for easy one-handed handling during inspection

Compatibility

Designed as a general-purpose Class ZZ plug pin gage for verifying 0.862 inch nominal bore diameters in standard go/no-go inspection procedures.

Installation Notes

Plug pin gages are handled by machinists and QC inspectors and do not require power tools or mechanical installation. Before use, clean the gage and the bore being inspected to remove chips, oil, or debris that could affect the reading. Store the gage in a protective case away from other tooling to prevent nicking the gage surface. Follow applicable ASME B89.1.5 gage standards for calibration intervals and handling procedures.
