Vermont Gage 111132100 Class Zz Plus Plug Gage 0.321 in

Product Description

The VERMONT GAGE 111132100 is a Class ZZ Plus plug gage designed for precision dimensional inspection of hole diameters. It measures a nominal diameter of 0.321 inches with a tolerance of 0.0002 inches, making it suitable for Go inspection applications where tight dimensional control is required. The gage features a 10 microfinish surface on the measuring element, which supports consistent, repeatable contact with the workpiece. Manufactured from tool steel, this gage is built for durability in shop and quality-control environments. It ships with a Certificate of Accuracy that includes NIST traceability, supporting documented calibration programs. Machinists, quality technicians, and tool-and-die professionals use this type of gage in production and inspection workflows.

This plug gage is used to verify that drilled, reamed, or bored holes fall within acceptable Go limits for a 0.321-inch diameter. It is appropriate for use alongside set micrometers, verniers, and other measuring devices in both shop-floor and lab inspection settings. The gage conforms to ASME B89.1 standards, making it suitable for facilities that require traceable, standards-compliant measurement tooling. It is commonly applied in light manufacturing, machining, and precision assembly environments where hole-size verification is a routine inspection step.

Compatibility

Designed for Go inspection use with set micrometers, verniers, and other measuring devices requiring a 0.321-inch diameter Class ZZ Plus plug gage reference.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power tools or electrical shutoff is required for use. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the workpiece bore before gauging to avoid false readings from chips or coolant residue. Follow your facility's calibration interval policy and the guidelines in ASME B89.1 to maintain traceability.
