Vermont Gage 111153000 Class Zz Plus Plug Gage 0.53 in

Product Description

The VERMONT GAGE 111153000 is a Class ZZ Plus plug gage designed to verify bore and hole diameters to a tight tolerance in production and inspection environments. Built from tool steel, this gage measures a nominal diameter of 0.53 inches with a tolerance of 0.0002 inches and a 10 microfinish surface finish. It ships with a Certificate of Accuracy traceable to NIST, making it ready for use in documented quality systems. Overall length is 2.0 inches. Machinists, quality control inspectors, and toolroom technicians rely on this type of gage for fast, repeatable attribute inspection of machined holes and bores.

This plug gage is configured for Go inspection, meaning it confirms a hole is no smaller than its minimum allowable diameter. It suits applications in job shops, production floors, and inspection labs where setting micrometers, verniers, and other measuring devices require a traceable reference standard. The 0.53-inch diameter range covers a common bore size found in general machining, fixture work, and mechanical assembly. Manufactured to ASME B89.1, this gage meets widely recognized dimensional metrology standards for plain plug gages.

Key Features

• Nominal measurement diameter of 0.53 inches for Go-style bore inspection
• Tolerance of 0.0002 inches for precise attribute gauging
• 10 microfinish surface on the gage member reduces wear and improves repeatability
• Tool steel construction provides durability in production inspection use
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Manufactured to ASME B89.1 standard for plain plug gages

Compatibility

Designed for Go inspection of holes and bores at 0.53 inches nominal diameter. Also suitable for setting micrometers, verniers, and other measuring devices requiring a traceable reference at this diameter.

Installation Notes

Plug gages are handled and used by quality technicians, machinists, and metrology personnel rather than installed in the traditional sense. Store the gage in its protective case when not in use and avoid dropping or contacting hard surfaces to preserve the precision finish. Clean the gage member and the part bore before inspection to prevent false readings or surface damage. Do not force the gage into a hole; apply only light hand pressure consistent with attribute gauging practice.
