Vermont Gage 112306710 Class Zz Plus Plug Gage 6.71mm

Product Description

The VERMONT GAGE 112306710 is a Class ZZ Plus plug gage machined from tool steel and finished to a 10 microfinish surface. It measures 6.71 mm in diameter with a tolerance of 0.00508 mm, making it suitable for precision go inspection applications. The overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. Machinists, quality technicians, and tool room professionals use this gage to verify bore and hole dimensions quickly and reliably on the shop floor or in an inspection environment.

This plug gage is intended for go inspection of bored, drilled, or reamed holes where tight dimensional control is required. It is also used to set and verify micrometers, verniers, and other measuring devices. Typical applications include incoming inspection, in-process quality checks, and final part verification in precision machining, tooling, and manufacturing environments. The Class ZZ Plus designation indicates a tighter tolerance class suitable for demanding inspection work.

Key Features

• 6.71 mm diameter with 0.00508 mm tolerance for precise go inspection
• Tool steel construction for durability and wear resistance
• 10 microfinish surface coating for accurate, repeatable contact
• Meets ASME B89.1 standards for plug gage dimensional requirements
• Includes Certificate of Accuracy with NIST traceability
• Compatible with go inspection use and as a setting standard for micrometers and verniers

Compatibility

Designed for go inspection of holes and bores at 6.71 mm diameter, and for use as a setting standard with micrometers, verniers, and other measuring devices requiring a certified reference.

Installation Notes

This gage is handled and used by quality technicians and machinists in inspection or tool room settings. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Do not force the gage into a bore; a go gage should pass under its own weight or with light hand pressure. Store in a protective case away from abrasive materials to preserve the 10 microfinish surface.
