Vermont Gage 111320850 Class Zz Plus Plug Gage 0.2085 in

Product Description

The VERMONT GAGE 111320850 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of hole and bore diameters. With a 0.2085 inch measurement diameter and a tolerance of 0.0002 inches, this gage delivers the precision required for go inspection work on production floors and in calibration labs. The 10 microfinish surface finish minimizes wear on the gage and the part being checked. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO and AS9100 quality systems. Licensed machinists, toolroom technicians, and quality control inspectors are the primary users of this instrument.

This plug gage is suited for verifying hole diameters in machined components across light manufacturing, aerospace, and precision mechanical assembly environments. It is also used as a reference standard for setting micrometers, verniers, and other measuring devices, making it a versatile calibration aid in any inspection department. The 2.0 inch overall length provides adequate reach for shallow blind holes and through-hole inspection at this diameter range.

Key Features

• Meets ASME B89.1 standard for plain plug gages
• Suitable for go inspection and as a setting standard for precision measuring instruments

Compatibility

Designed for go inspection of 0.2085 inch diameter holes and bores, and for use as a setting reference for micrometers, verniers, and other precision measuring devices as noted in the manufacturer application data.

Installation Notes

Plug gages are handled and used by quality control technicians and toolroom personnel; no power source or shutoff is required. Clean the gage and the part to be inspected before use to prevent false readings caused by chips or coolant residue. Store the gage in its protective case when not in use to preserve the microfinish surface and maintain calibration integrity. Periodic recalibration against a NIST-traceable master is recommended per your facility quality plan.
