Spi 29-192-2 Class Zz Plus Plug Gage 0.192 in

Product Description

The SPI 29-192-2 is a Class ZZ Plus plug gage used to verify hole diameters to a precise tolerance of 0.0002 inches (0.0051 mm). Machined from steel, this go/no-go style gage is a standard inspection tool for quality control in machine shops, toolrooms, and manufacturing environments. At 0.192 inches in diameter, it is suited for checking small-bore features on machined parts, castings, and assemblies. Licensed metrologists, machinists, and QC inspectors rely on plug gages like this one to confirm that drilled, reamed, or bored holes fall within specified tolerances before parts move to assembly.

This gage is designed for inspection of 0.192-inch diameter holes in production and toolroom settings. It is commonly used in metalworking, aerospace component inspection, automotive parts manufacturing, and general precision machining applications where tight dimensional control is required. Its compact size makes it practical for bench inspection as well as in-process checks on the shop floor.

Key Features

• Class ZZ Plus tolerance rating of 0.0002 inches for high-precision hole verification
• 0.192-inch nominal diameter for small-bore inspection
• Steel construction for durability and wear resistance in production environments
• Compact and lightweight at 0.2 pounds for easy handling during inspection
• Single-piece package quantity suitable for individual toolroom and QC use

Compatibility

Designed as an OEM-style replacement or direct-use plug gage for inspection of 0.192-inch nominal diameter holes in steel, aluminum, and other machined workpieces where Class ZZ Plus tolerances are specified.

Installation Notes

Plug gages are handled and used by machinists, toolroom technicians, and quality control inspectors. Before use, clean both the gage and the hole being checked to remove chips, coolant, or debris that could affect the reading. Do not force the gage into the hole; excessive insertion force can damage the gage surface and produce false readings. Store the gage in a protective case away from abrasive materials to preserve its calibrated tolerance.
