Vermont Gage 111124600 Class Zz Plus Plug Gage 0.246 in

Product Description

The VERMONT GAGE 111124600 is a Class ZZ Plus plug gage used to perform go inspection checks on precision bores and holes. Measuring 0.246 inches in diameter, this single-ended plug gage is machined from tool steel and finished to a 10 microfinish surface for consistent, repeatable contact. It carries an ASME B89.1 tolerance of 0.0002 inches, placing it firmly in the ZZ Plus accuracy class. Each unit ships with a Certificate of Accuracy with NIST Traceability, making it a valid reference tool in calibrated inspection workflows. Machinists, quality technicians, and tool-and-die professionals use this gage for verifying hole dimensions on precision parts.

This plug gage is suited for incoming inspection, in-process quality checks, and calibration verification of measuring devices such as set micrometers, verniers, and other dimensional measuring instruments. It is appropriate for use in both production floor environments and metrology labs where ASME B89.1 compliance is required. The compact overall length of 2.0 inches makes it easy to handle for repetitive inspection tasks on standard machined components.

Compatibility

Designed as an OEM-style go inspection plug gage for use with set micrometers, verniers, and other dimensional measuring devices requiring a 0.246 inch diameter reference standard compliant with ASME B89.1.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists in accordance with ASME dimensional inspection standards. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean contact surfaces with a lint-free cloth before each use to ensure accurate measurement. Do not apply excessive insertion force, as this can damage both the gage and the workpiece bore.
