Spi 19-083-5 Class Zz Minus Plug Pin Gage 0.083 in

Product Description

The SPI 19-083-5 is a Class ZZ minus plug pin gage designed for go/no-go dimensional inspection of drilled, reamed, or bored holes. The gage checks whether a 0.083-inch diameter hole falls within acceptable tolerance limits. Built from steel, this single-ended pin gage is used in quality control and incoming inspection settings where repeatable, traceable measurement is required. The Class ZZ designation indicates a commercial-grade tolerance standard, and the minus designation means the gage is made to the lower end of the tolerance range, holding 0.000200 inches total tolerance. Machinists, quality technicians, and tool room inspectors rely on this type of gage for fast, low-cost attribute inspection.

This pin gage is suited for light production inspection and general shop use where Class ZZ tolerances meet the required inspection standard. Typical applications include verifying hole diameters in machined metal components, plastic parts, and fabricated assemblies. It is appropriate for any shop or inspection department that needs a simple, reliable attribute gage for holes in the 0.083-inch range.

Key Features

• Class ZZ minus designation for commercial-grade go/no-go hole inspection
• 0.083-inch nominal diameter for precise small-hole checking
• 0.000200-inch tolerance for consistent, repeatable results
• Steel construction for durability and wear resistance in shop environments
• Single-piece design requires no setup before use

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use with pin gage handles and sets compatible with 0.083-inch diameter pins in commercial inspection 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 other metal tools to avoid contact damage to the gage surface. Verify the gage is at room temperature before use, as thermal expansion can affect readings. Periodic cleaning and re-oiling with a light instrument oil will extend service life.
