Vermont Gage 111306550 Class Zz Plus Plug Gage

Product Description

The VERMONT GAGE 111306550 is a Class ZZ Plus plug gage designed for precision go-inspection work in dimensional quality control applications. It measures a nominal diameter of 0.0655 inches with a tolerance of 0.0002 inches, making it suitable for verifying small-bore dimensions with high repeatability. Manufactured from tool steel with a 10 microfinish surface, this gage delivers the surface consistency required for reliable contact measurement. Each unit ships with a Certificate of Accuracy backed by NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this type of gage in production and inspection environments.

This plug gage is used in dimensional inspection of drilled, reamed, or bored holes where close tolerances must be verified. Its small diameter makes it appropriate for precision machined components, instrument housings, and similar fine-tolerance work. It is also suited for calibrating and setting micrometers, verniers, and other measuring devices. The NIST-traceable certification supports use in quality systems requiring documented measurement traceability, including ISO 9001 and AS9100 environments.

• 10 microfinish surface finish ensures consistent gage-to-bore contact
• Tool steel construction provides durability and wear resistance in production use
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards for plain plug gages
• Overall length of 2.0 inches for comfortable single-hand use

Compatibility

Designed for go-inspection of holes and bores with a nominal diameter of 0.0655 inches. Also used for setting and verifying micrometers, verniers, and other dimensional measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no installation in the traditional sense applies. Before use, clean both the gage and the bore with a lint-free cloth to remove chips, oil, or debris that could affect measurement accuracy. Do not force the gage into an undersized bore, as this can damage the gage surface and invalidate the measurement. Store the gage in its protective case when not in use to prevent corrosion and surface damage.
