Vermont Gage 111129800 Class Zz Plus Plug Gage 0.298 in

Product Description

The VERMONT GAGE 111129800 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored, drilled, and reamed holes. It measures a nominal diameter of 0.298 inches with a tolerance of 0.0002 inches, delivering the accuracy required for go inspection work. The gage is manufactured from tool steel and features a 10 microfinish surface, which supports consistent, repeatable contact during measurement. It ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, tool room technicians, and quality control inspectors rely on this type of gage for verifying hole dimensions in production and inspection environments.

This plug gage is suited for go inspection applications in machine shops, manufacturing facilities, and metrology labs. It is used alongside set micrometers, verniers, and other precision measuring devices to confirm that drilled or bored holes fall within specified tolerances. The 0.298-inch diameter and 2.0-inch overall length make it practical for use in a wide range of workpieces encountered in general metalworking and precision machining operations.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• Tool steel construction for durability and wear resistance in production use
• 10 microfinish surface for consistent, low-friction gage contact
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards
• Compact 2.0-inch overall length for versatile workpiece access

Compatibility

Designed as an OEM-style precision measurement tool for go inspection use with set micrometers, verniers, and other measuring devices in standard machine shop and quality control applications.

Installation Notes

Plug gages are handled and used by machinists and quality technicians, not installed in the field sense. Store the gage in its case when not in use to protect the lapped surface from damage or corrosion. Clean the gage and the bore with a lint-free cloth before use to prevent debris from affecting readings. Never force the gage into a hole; if resistance is encountered, the bore is undersized and should be reworked before re-inspection.
