Vermont Gage 111328450 Class Zz Plus Plug Gage 0.2845 in

Product Description

The VERMONT GAGE 111328450 is a Class ZZ Plus plug gage designed to verify bore and hole dimensions with high accuracy. It measures a nominal diameter of 0.2845 inches and holds a tolerance of 0.0002 inches, making it suitable for go inspection applications. The gage is manufactured from tool steel and features a 10 microfinish surface coating for consistent, repeatable contact. Metrology technicians, machinists, and quality control inspectors use this gage to confirm dimensional conformance on production and incoming inspection lines. Each unit ships with a Certificate of Accuracy with NIST Traceability.

This plug gage is used wherever precise hole-diameter verification is required. Typical applications include go inspection of drilled, reamed, or bored holes at 0.2845 inches nominal. It is also used to calibrate and verify the accuracy of micrometers, verniers, and other hand-measuring devices. Suited to both job-shop and production-floor environments, the 111328450 fits cleanly into standard gage-block and plug-gage handling workflows. Its compact 2.0-inch overall length allows easy handling in confined inspection setups.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel. Always handle with clean, dry hands or lint-free gloves to avoid introducing measurement error from skin oils or debris. Store in a protective case away from impact and temperature extremes to maintain dimensional accuracy.
