Spi 19-199-9 Class Zz Minus Plug Pin Gage 0.199 in

Product Description

The SPI 19-199-9 is a Class ZZ minus plug pin gage with a 0.199-inch nominal diameter, designed for go/no-go inspection and dimensional verification in production and quality control environments. Built from steel, this pin gage holds a tolerance of 0.0002 inches, meeting Class ZZ specifications for minus-type gages. It is used to verify that a hole or bore meets minimum acceptable size requirements. Machinists, toolmakers, quality technicians, and inspection personnel use these gages as part of standard dimensional inspection workflows on the shop floor or in the inspection lab.

This pin gage is suited for inspecting drilled, reamed, or bored holes in metal, plastic, and composite workpieces. At 0.199 inches in diameter with a Class ZZ minus designation, it functions as a no-go member in paired gage sets or as a standalone check for minimum hole size acceptance. Typical applications include incoming inspection, in-process quality checks, and final part verification in manufacturing and fabrication settings.

Key Features

• Class ZZ minus tolerance designation for no-go or minimum-size hole inspection
• 0.0002-inch tolerance for reliable dimensional verification at this diameter range
• Steel construction for durability and dimensional stability during repeated use
• Nominal diameter of 0.199 inches for precise small-bore inspection
• Compact and lightweight at 0.2 pounds for easy handling at the inspection station

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use with compatible pin gage handles and holders sized for small-diameter pins in the 0.199-inch range.

Installation Notes

Pin gages are handled by quality technicians and toolroom personnel and require no installation in the traditional sense. Store and transport the gage in a protective case to prevent surface damage that could affect dimensional accuracy. Clean the gage and the workpiece bore before use to remove chips, oils, or debris that could cause a false reading. Handle with care to avoid dropping, as impact can alter the gage diameter and compromise calibration.
