Vermont Gage 111327050 Class Zz Plus Plug Gage 0.2705 in

Product Description

The VERMONT GAGE 111327050 is a Class ZZ Plus plug gage machined from tool steel for precision dimensional inspection. It measures a nominal diameter of 0.2705 inches with a tolerance of 0.0002 inches, making it suitable for tight go-inspection work where part conformance must be verified against a fixed limit. The gage features a 10 microfinish surface, which supports accurate, repeatable contact with the workpiece. Every unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements in quality-controlled manufacturing and metrology environments. Machinists, quality technicians, and tool-and-die professionals use this gage as part of routine SPC and first-article inspection workflows.

This plug gage is used in go inspection of drilled, reamed, or bored holes at 0.2705 inches nominal diameter. It is also suited for setting and verifying micrometers, verniers, and other bench measuring devices to a known reference standard. Applications span production machining shops, toolrooms, and quality labs in both job-shop and high-volume manufacturing settings. The Class ZZ Plus designation indicates a commercial-grade tolerance class appropriate for general-purpose inspection rather than master or reference gage applications. Typical users include QC inspectors and machinists working to ASME B89.1 dimensional standards.

Key Features

• 0.2705 inch nominal measurement diameter for go inspection of correspondingly sized bores and holes
• 0.0002 inch tolerance class meets ASME B89.1 requirements for Class ZZ Plus plug gages
• 10 microfinish surface finish supports consistent, low-wear contact during repeated use
• Tool steel construction provides durability and dimensional stability in shop environments
• Certificate of Accuracy with NIST traceability included, supporting ISO and AS9100 documentation needs
• Compatible use as a setting standard for micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of holes and bores at 0.2705 inches nominal diameter and for use as a setting reference with micrometers, verniers, and other measuring devices, per the manufacturer application data.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power-down or mechanical installation is required. Store the gage in its protective case when not in use and handle with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Verify the gage is at ambient temperature before use, as thermal expansion can affect readings. Clean the gage and the bore being checked before inspection to remove chips, coolant, and debris that could cause a false rejection or damage the gage surface.
