Vermont Gage 911107500 Class Zz Plus Plug Gage 0.075 in

Product Description

The VERMONT GAGE 911107500 is a Class ZZ Plus plug gage designed to verify bore and hole diameters with precision. Measuring 0.075 inches in diameter with a tolerance of 0.0002 inches, this gage delivers the accuracy required for go inspection tasks across machining and manufacturing environments. Constructed from tool steel with a black oxide finish, it resists corrosion and wear under regular shop use. Overall length is 2.0 inches, making it easy to handle during inspection. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming it meets ASME B89.1 standards. Machinists, quality control technicians, and metrology professionals rely on this type of gage to validate part conformance before and after machining operations.

This plug gage is suited for go inspection of small-diameter holes and bores in precision machining, toolroom, and quality assurance applications. It is also used to set and verify micrometers, verniers, and other measuring devices that require a calibrated reference. Typical users include machinists, CNC operators, and QC inspectors working with tight-tolerance components in aerospace, automotive, or general manufacturing. The compact size and standardized diameter make it a practical addition to any inspection station handling sub-0.1-inch bore work.

Key Features

• 0.075 inch measurement diameter with a 0.0002 inch tolerance for precise go inspection
• Tool steel construction provides durability and dimensional stability under repeated use
• Black oxide finish offers corrosion resistance in typical shop environments
• Meets ASME B89.1 standards for dimensional gaging
• Includes Certificate of Accuracy with NIST traceability for documentation and calibration records
• 2.0 inch overall length for comfortable handling during inspection tasks

Compatibility

Designed for use in go inspection of holes and bores at 0.075 inches diameter, and as a setting standard for micrometers, verniers, and other precision measuring devices requiring a calibrated reference at this diameter.

Installation Notes

Plug gages of this type are handled and applied by machinists or QC technicians and require no power or mechanical installation. Store the gage in its protective case when not in use to prevent surface damage that could affect dimensional accuracy. Clean the gage and the bore to be inspected before use to avoid false readings from debris or oils. Follow your facility calibration program and ASME B89.1 handling guidelines to maintain traceability.
