Spi 19-061-1 Class Zz Minus Plug Pin Gage 0.061 in

Product Description

The SPI 19-061-1 is a Class ZZ minus plug pin gage measuring 0.061 inches in diameter, designed for go/no-go inspection work in precision measurement applications. Manufactured from steel, this pin gage holds a tolerance of 0.0002 inches, conforming to Class ZZ minus specifications for inspection-grade gauging. It is used to verify hole diameters and internal dimensions where tight tolerances are critical. Quality control technicians, machinists, and tool and die professionals rely on Class ZZ pin gages for reliable, repeatable dimensional inspection across production and maintenance environments.

This pin gage is suited for dimensional inspection of drilled, reamed, or punched holes in manufacturing, tooling, and quality assurance settings. At 0.061 inches diameter with a minus tolerance designation, it is intended to verify the lower boundary of a tolerance range, ensuring holes do not fall below the minimum acceptable size. Typical applications include incoming inspection, in-process gauging, and final verification on precision parts in light manufacturing and machining shops.

Key Features

• Class ZZ minus designation for inspection-grade go/no-go gauging
• 0.061 inches diameter with 0.0002 inches tolerance for precise measurement
• Steel construction for durability and dimensional stability
• Compact, single-pin format for easy handling and storage
• Packaged individually, ready for immediate use or gage set integration

Compatibility

Designed as an OEM-style inspection tool compatible with standard pin gage handles and gage block sets used in general precision measurement and quality control applications.

Installation Notes

Pin gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in a protective case away from temperature extremes to maintain dimensional accuracy. Clean mating holes and the pin surface before gauging to ensure accurate readings. Do not force the pin into an undersized hole, as this can damage the gage or alter its calibrated tolerance.
