Vermont Gage 112106740 Class Zz Plus Plug Gage 6.74mm

Product Description

The VERMONT GAGE 112106740 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of bored, drilled, and reamed holes. It checks whether a hole meets minimum acceptable size, rejecting undersize work before it moves downstream. The gage measures 6.74 mm in diameter with a tolerance of 0.00508 mm and carries a 10 microfinish surface finish, delivering repeatable, high-confidence results in production and inspection environments. An overall length of 2.0000 inches keeps it compact and easy to handle in tight workholding setups. A Certificate of Accuracy with NIST Traceability ships with the gage, meeting the documentation requirements of quality management systems.

This plug gage is suited for toolroom, production floor, and incoming inspection use wherever close-tolerance hole verification is required. Typical applications include verifying drilled and reamed bores in machined components across industries such as aerospace, automotive, and general manufacturing. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a certified reference standard. The compact form factor and single-piece configuration make it practical for both bench inspection and inline checking at the machine.

Key Features

• Class ZZ Plus tolerance grade for go inspection of 6.74 mm diameter holes
• Tolerance of 0.00508 mm for high-precision dimensional verification
• 10 microfinish surface for consistent, low-wear gauge contact
• Tool steel construction for durability in production inspection environments
• Overall length of 2.0000 inches for compact, easy handling
• Includes Certificate of Accuracy with NIST Traceability, conforming to ASME B89.1

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle sets and applicable to any inspection workflow requiring ASME B89.1 compliant Class ZZ Plus plug gage standards at the 6.74 mm diameter size.

Installation Notes

Plug gages of this type are handled and applied by quality technicians, toolroom machinists, and inspection personnel - not installed in the conventional sense. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the hole being checked before use to avoid false readings caused by chips or coolant residue. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity over time.
