Vermont Gage 111314250 Class Zz Plus Plug Gage 0.1425 in

Product Description

The VERMONT GAGE 111314250 is a Class ZZ Plus plug gage manufactured from tool steel and used to verify bore and hole dimensions to tight tolerance in production and inspection environments. This gage measures a nominal diameter of 0.1425 inches with a tolerance of 0.0002 inches and a surface finish of 10 microfinish, making it suitable for applications where dimensional accuracy is critical. It ships with a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. Licensed metrologists, quality technicians, and precision machinists use this gage as part of go-inspection routines to confirm that features are within print specifications.

This plug gage is designed for go inspection workflows where a hole, bore, or similar feature must be confirmed to accept the gage without force. Typical applications include calibrating and verifying the accuracy of set micrometers, verniers, and other measuring devices, as well as incoming and in-process inspection of machined parts. The 0.1425-inch diameter suits small-bore inspection tasks common in precision manufacturing, toolroom work, and quality control labs. Its 2.0-inch overall length provides comfortable handling for bench inspection use.

Key Features

• Class ZZ Plus tolerance grade with 0.0002-inch tolerance for reliable go-inspection accuracy
• 10 microfinish surface finish minimizes wear on precision bores during repeated use
• Tool steel construction provides durability under regular shop and lab conditions
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards
• 2.0-inch overall length supports easy single-hand use at the bench

Compatibility

Designed for use as a go plug gage for holes and bores with a nominal diameter of 0.1425 inches. Also suitable for setting and verifying micrometers, verniers, and other precision measuring devices requiring a reference of this size.

Installation Notes

Plug gages are handled and used by quality technicians and precision machinists; no installation trade license is required. Always clean the gage and the feature being inspected before use to prevent debris-related false readings or surface damage. Never force a go gage into a feature — if resistance is felt, the feature is undersize. Store in a case or on a padded surface away from other tooling to protect the lapped surface finish and dimensional integrity.
