Vermont Gage 112305970 Class Zz Plus Plug Gage 5.97 Mm

Product Description

The VERMONT GAGE 112305970 is a Class ZZ Plus cylindrical plug gage with a 5.97 mm diameter, designed for go inspection of bored holes, machined ports, and precision-toleranced features. Manufactured from tool steel with a 10 microfinish surface, it delivers a tolerance of 0.00508 mm to ensure reliable pass/fail measurement at the inspection bench or on the shop floor. Each gage ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. It is suited for machinists, quality technicians, and tool room personnel who require consistent, repeatable inspection tooling.

This plug gage is used in precision inspection applications where hole diameter conformance must be verified quickly and accurately. Typical use cases include incoming inspection, in-process quality checks, and final verification on machined components. It is also compatible with go inspection routines using set micrometers, verniers, and other calibrated measuring devices. The 2.0-inch overall length makes it easy to handle and well-suited to bench inspection setups in both production and tool room environments.

Key Features

• Class ZZ Plus designation meets ASME B89.1 dimensional standards for plug gages
• 5.97 mm diameter with a tolerance of 0.00508 mm for precise go inspection
• Tool steel construction provides durability and wear resistance in daily inspection use
• 10 microfinish surface reduces friction and wear on precision bores during gauging
• Includes Certificate of Accuracy with NIST traceability for calibration compliance
• Compact 2.0-inch overall length suits bench inspection and handheld use

Compatibility

Designed for go inspection of precision-machined holes and bores; also compatible with set micrometers, verniers, and other measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and applied by machinists, quality technicians, and metrology personnel - no power tools or utilities need to be shut off prior to use. Store the gage in a protective case away from moisture and abrasive surfaces to preserve the microfinish and dimensional accuracy. Clean the gage and bore with a lint-free cloth before inspection to prevent debris from affecting readings. Follow your facility calibration schedule and reference the included NIST-traceable certificate to maintain measurement traceability.
