Spi 19-192-4 Class Zz Minus Plug Pin Gage 0.192 in

Product Description

The SPI 19-192-4 is a Class ZZ minus plug pin gage with a 0.192-inch diameter, manufactured from steel for reliable dimensional inspection work. This go/no-go style pin gage is used to verify hole diameters and bore tolerances in machined components, castings, and fabricated parts. It carries a minus tolerance of 0.0002 inches, placing it within Class ZZ specifications for general-purpose inspection. Machinists, quality control technicians, and toolroom professionals use plug pin gages like this to confirm that drilled or reamed holes fall within acceptable dimensional limits before parts move to the next stage of production or assembly.

This 0.192-inch plug pin gage is suited for general-purpose dimensional inspection in manufacturing, machining, and toolroom environments. It is appropriate for checking hole sizes in metal, plastic, and composite workpieces where tight tolerances must be verified. The Class ZZ designation makes it a practical choice for in-process checks and incoming inspection tasks where high-precision Class Z or ZZ gaging is required but a laboratory-grade master gage is not necessary.

Key Features

• Class ZZ minus tolerance specification for general-purpose hole inspection
• 0.192-inch nominal diameter for precise bore verification
• 0.0002-inch tolerance (0.0002 mm) for consistent, repeatable measurement
• Steel construction for durability in production and toolroom use
• Single-piece package ready for immediate use

Compatibility

Designed as a general-purpose Class ZZ plug pin gage for dimensional inspection of 0.192-inch nominal diameter holes in machined parts, castings, and fabricated components across manufacturing and toolroom applications.

Installation Notes

Plug pin gages are handled and stored by quality control and toolroom personnel following standard gage-handling procedures. Always clean and deburr the hole being checked before inserting the gage to avoid surface damage or false readings. Store pin gages in a protective case or holder away from contaminants and temperature extremes to preserve dimensional accuracy. Periodic recalibration against traceable standards is recommended per applicable quality management requirements.
