Spi 19-118-9 Class Zz Minus Plug Pin Gage 0.1180 in

Product Description

The SPI 19-118-9 is a Class ZZ minus plug pin gage used to verify hole diameters and bore sizes in precision inspection and quality control applications. Sized at 0.1180 inches in diameter with a tolerance of 0.0002 inches, this gage provides a reliable go/no-go reference for checking small bores to Class ZZ standards. Machined from steel for durability and dimensional stability, it is a straightforward tool for machinists, toolmakers, and quality technicians working in production or inspection environments where close tolerances must be confirmed quickly and accurately.

This pin gage is suited for use in machine shops, manufacturing facilities, and inspection labs where small-diameter bore verification is part of standard workflow. The minus designation means the gage is manufactured to the lower tolerance boundary, making it appropriate for go-gage applications where confirming minimum acceptable hole size is required. Typical users include machinists, metrology technicians, and quality assurance personnel working with tight-tolerance components.

Key Features

• Class ZZ tolerance grade for general-purpose inspection use
• Minus designation suits go-gage and minimum bore verification applications
• 0.1180-inch diameter with 0.0002-inch tolerance for precise fit confirmation
• Steel construction provides dimensional stability and wear resistance
• Compact single-pin format for straightforward manual inspection

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use with pin gage handles and sets compatible with 0.1180-inch diameter pins in general-purpose bore inspection applications.

Installation Notes

Pin gages are handled and used by machinists and metrology technicians following standard inspection procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a bore, as this can damage both the gage and the workpiece. Store in a protective case away from surfaces that could cause nicks or dimensional distortion.
