Spi 19-117-1 Class Zz Minus Plug Pin Gage 0.1170 in

Product Description

The SPI 19-117-1 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 0.1170 inches with a minus tolerance of 0.0002 inches, placing it within the Class ZZ specification for go/no-go functional gauging. Constructed from steel, this pin gage is a standard tool in quality control environments where dimensional verification of drilled, reamed, or punched holes is required. Machinists, tool and die makers, and quality inspection technicians use this type of gage to confirm that a hole falls within the lower boundary of its tolerance band.

This pin gage is suited for use in machine shops, manufacturing facilities, and inspection departments working with small-diameter holes in metal, plastic, or composite workpieces. It is appropriate for both production floor spot-checking and formal inspection setups. The 0.1170-inch diameter covers a common drill size range, making it a practical addition to a gage pin set used in general metalworking or precision assembly applications.

• Tolerance of 0.0002 inches ensures precise dimensional verification
• Steel construction provides durability and wear resistance for repeated use
• Compact single-pin format for easy handling and direct insertion into bore
• Sold individually, suitable as a standalone replacement or set supplement

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in go/no-go hole inspection applications requiring a 0.1170-inch nominal diameter check.

Installation Notes

Pin gages are handled and used by quality technicians or machinists; no power source or lockout procedure is required. Clean the gage and the hole being measured before use to avoid false readings caused by chips or debris. Do not force the pin into an undersized hole, as this can damage the gage or alter its calibration. Store pin gages in a protective case and handle with clean, dry hands or cotton gloves to prevent corrosion.
