Vermont Gage 111166200 Class Zz Plus Plug Gage 0.662 in

Product Description

The VERMONT GAGE 111166200 is a Class ZZ Plus plug gage with a 0.662-inch measurement diameter, designed for dimensional inspection of machined bores and holes. It provides a tolerance of 0.0002 inches and a 10 microinch surface finish, delivering the precision required for go inspection tasks. Manufactured from tool steel, this gage delivers the hardness and wear resistance needed for repeated use in shop-floor and metrology environments. It ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality-control documentation requirements. Machinists, quality technicians, and tool-and-die professionals use this gage as part of standard attribute inspection workflows.

This plug gage is applied in go inspection routines to verify that a machined feature meets its minimum size requirement. It is also used to set and verify micrometers, verniers, and other comparative measuring devices. Typical environments include production machining shops, inspection labs, and toolrooms where ASME B89.1 dimensional standards govern measurement practice. The 2.0-inch overall length provides a comfortable handle for single-hand operation during routine inspection passes.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• 0.662-inch nominal diameter machined to ASME B89.1 standards
• 10 microinch surface finish for consistent, low-friction gauge contact
• Tool steel construction for hardness and long service life
• Includes Certificate of Accuracy with NIST traceability for QC documentation
• 2.0-inch overall length for easy single-hand use

Compatibility

Designed for go inspection of bores and holes at 0.662 inches nominal diameter, and suitable for setting micrometers, verniers, and other measuring devices per ASME B89.1 practice.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or fasteners are required. Clean the gage and the part bore before each use to prevent debris from affecting the measurement result. Store the gage in its protective case when not in use to preserve the surface finish and dimensional accuracy. Handle with care to avoid dropping, as impact can alter the calibrated diameter and invalidate NIST traceability.
