Vermont Gage 911107000 Class Zz Plus Plug Gage 0.07 in

Product Description

The VERMONT GAGE 911107000 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes. Manufactured from tool steel with a black oxide finish, this go-type plug gage measures a nominal diameter of 0.07 inches with a tolerance of 0.0002 inches. The 2-inch overall length provides a stable grip for hand-held use. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming dimensional conformance to ASME B89.1. Licensed metrology technicians and quality control inspectors rely on this gage to verify bore acceptance in production and inspection environments.

This plug gage is suited for go inspection applications across precision machining, manufacturing, and quality assurance settings. It is also used to calibrate and verify the accuracy of micrometers, vernier calipers, and other measuring devices where a traceable reference standard is required. The 0.07-inch diameter makes it appropriate for inspecting small-bore features commonly found in precision mechanical assemblies. Both light industrial and high-tolerance production shops use this tool as part of routine dimensional verification workflows.

Key Features

• Class ZZ Plus tolerance rating of 0.0002 inches for high-precision go inspection
• Tool steel construction for durability and dimensional stability
• Black oxide finish reduces surface reflectivity and provides corrosion resistance
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards for dimensional gaging
• Compatible with go inspection setups, micrometer sets, verniers, and other measuring devices

Compatibility

Designed for go inspection applications and suitable for use with micrometers, verniers, and other measuring devices requiring a traceable reference standard at 0.07 inches nominal diameter.

Installation Notes

Handle plug gages with clean, dry hands or cotton inspection gloves to prevent contamination from skin oils, which can affect surface finish and dimensional readings. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface. Inspect the gage surface for nicks or wear before each use, and recertify or replace the gage if wear exceeds tolerance limits. Cleaning with a lint-free cloth and light instrument oil is recommended before and after use.
