Spi 19-882-0 Class Zz Minus Plug Pin Gage 0.882 in

Product Description

The SPI 19-882-0 is a Class ZZ minus plug pin gage designed to verify bore diameters and hole tolerances in precision machining and inspection applications. The gage measures 0.882 inches in diameter and is manufactured from steel for durability under repeated use. With a tolerance of 0.0002 inches, this minus-type gage represents the lower allowable limit of the nominal dimension, making it suitable for go/no-go inspection workflows where tight dimensional control is required. Metrologists, machinists, and quality control technicians use Class ZZ plug gages as an economical tool for production-floor and inspection-room dimensional verification.

Class ZZ plug pin gages are commonly used in light-duty inspection environments, including job shops, production lines, and quality assurance labs. This gage is appropriate for checking hole sizes in machined components, castings, and fabricated parts where dimensional accuracy must be confirmed before assembly or shipment. The minus designation indicates the gage is ground to the lower boundary of the tolerance band, consistent with standard go-gage practice for verifying minimum acceptable hole size.

Key Features

• 0.882-inch diameter for direct bore and hole verification at that nominal size
• Class ZZ tolerance classification suitable for general-purpose inspection and production use
• Minus-type ground to 0.0002-inch tolerance for lower-limit dimensional checking
• Steel construction provides wear resistance under repeated insertion cycles
• Compact single-pin format for easy handheld use on the production floor or in the inspection lab

Compatibility

Designed as a standard Class ZZ minus plug pin gage for general-purpose dimensional inspection of 0.882-inch nominal bore diameters in machined components and fabricated parts.

Installation Notes

Plug pin gages are handled and used by machinists, metrologists, and quality technicians — no installation tools or power sources are required. Clean the gage and the bore being checked before each use to prevent debris from affecting measurement accuracy. Store gages in a protective case away from moisture and temperature extremes to preserve calibration. Periodic recalibration against traceable standards is recommended to maintain measurement integrity over the life of the gage.
