Vermont Gage 911104600 Class Zz Plus Plug Gage 0.046 in

Product Description

The VERMONT GAGE 911104600 is a Class ZZ Plus plug gage designed to perform go-side dimensional inspection on small-diameter bores and holes. Built from tool steel with a black oxide finish, this gage measures a nominal diameter of 0.046 inches and holds a tolerance of 0.0002 inches. At 2.0 inches in overall length and weighing just 0.1 pounds, it is a compact, single-ended precision tool. Each unit ships with a Certificate of Accuracy that includes NIST traceability, confirming it meets ASME B89.1 standards. Machinists, quality technicians, and tool-and-die professionals rely on plug gages like this one to verify bore dimensions quickly and consistently on the shop floor or in the inspection lab.

This gage is suited for go-side inspection of drilled, reamed, or otherwise finished small-diameter holes where tight dimensional control is required. It is also used to set and verify the accuracy of micrometers, verniers, and other precision measuring devices. Typical applications include incoming inspection, in-process quality checks, and final acceptance inspection in precision machining, aerospace, automotive, and general manufacturing environments. The small diameter makes it particularly appropriate for work involving instrument bores, pilot holes, and fine-tolerance components.

Key Features

• Class ZZ Plus tolerance class for go-side bore inspection per ASME B89.1
• 0.046 inches nominal diameter with 0.0002 inches tolerance for precise dimensional verification
• Tool steel construction provides durability and resistance to wear under repeated use
• Black oxide finish reduces surface reflectivity and offers mild corrosion resistance
• Includes Certificate of Accuracy with NIST traceability for documented quality assurance
• Compact 2.0 inches overall length suited for bench and handheld inspection use

Compatibility

Designed for go-side inspection of small-diameter bores and for use as a reference standard when setting micrometers, verniers, and other precision measuring instruments. Compatible with standard plug gage handles and holders sized for small-diameter gaging members.

Installation Notes

Plug gages are handled and used by quality technicians and precision machinists rather than installed in a traditional mechanical sense. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface. Clean the gage and the bore with a lint-free cloth before inspection to remove chips, oil, or debris that could affect readings. Do not force the gage member into an undersized bore, as this can damage both the gage and the workpiece.
