Vermont Gage 111119700 Class Zz Plus Plug Gage 0.197 in

Product Description

The VERMONT GAGE 111119700 is a Class ZZ Plus plug gage machined from tool steel and designed for go inspection of bored, reamed, or drilled holes at a nominal diameter of 0.197 inches. It holds a tolerance of 0.0002 inches and features a 10 microfinish surface, delivering the dimensional accuracy required for production inspection and quality control work. Overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for calibration-documented inspection environments. Machinists, quality technicians, and tool room personnel are the primary users of this gage.

This plug gage is used in manufacturing and machine shop environments where holes must be verified against tight dimensional tolerances before assembly. It is well suited for use alongside set micrometers, verniers, and other precision measuring devices in both incoming inspection and in-process quality checks. The 0.197-inch diameter range addresses common drilled and reamed hole sizes in light to medium precision work. Applications span general metalworking, tool and die, and production inspection across a range of industries.

Key Features

• Class ZZ Plus tolerance grade — holds 0.0002 inches for reliable go-side inspection
• 10 microfinish surface for consistent, low-wear contact with inspected bores
• Tool steel construction provides durability in production inspection use
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability for documented calibration chains
• Compact 2.0-inch overall length suits bench and hand-held inspection tasks

Compatibility

Designed for go inspection of holes at 0.197 inches nominal diameter. Compatible for use with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no power tools or utilities need to be shut down for gage use. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surfaces. Do not force the gage into a hole; go-side gages should enter under light hand pressure only. Store in a protective case away from other tools to preserve the lapped surface finish and dimensional integrity.
