Vermont Gage 911105300 Class Zz Plus Plug Gage 0.053 in

Product Description

The VERMONT GAGE 911105300 is a Class ZZ Plus plug gage used to verify bore and hole dimensions during precision inspection work. It measures a nominal diameter of 0.053 inches with a tolerance of 0.0002 inches, making it suitable for go-type inspection checks where tight dimensional control is required. The gage body is machined from tool steel and finished with a black oxide coating for corrosion resistance and durability. Overall length is 2.0 inches. A Certificate of Accuracy with NIST traceability is included, supporting quality documentation requirements in production and metrology environments. Machinists, quality technicians, and tool-and-die professionals use this gage in standard inspection workflows.

This plug gage is used in go inspection applications where small-diameter hole acceptance needs to be confirmed quickly and accurately. It is also suited for setting and verifying micrometers, verniers, and other measuring devices that require a traceable reference standard. The 0.053-inch diameter range makes it appropriate for precision machined components, tooling fixtures, and small-bore inspection tasks in both production and quality lab environments. It conforms to ASME B89.1 standards, which is the governing specification for plain plug gages used in dimensional metrology.

Key Features

• 0.053-inch nominal diameter with 0.0002-inch tolerance for tight go-inspection accuracy
• Class ZZ Plus classification per ASME B89.1 dimensional metrology standards
• Tool steel construction for hardness and wear resistance in repeated use
• Black oxide finish provides corrosion resistance without altering dimensional integrity
• Includes Certificate of Accuracy with NIST traceability for quality recordkeeping
• 2.0-inch overall length for easy handling in bench and floor inspection settings

Compatibility

Designed for go inspection of holes and bores at 0.053 inches nominal diameter, and for use as a reference standard when setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no power tools or utility shutoff procedures apply. Handle the gage with clean, dry hands or cotton gloves to prevent contamination of the measuring surface. Store in a protective case away from other tooling to prevent contact damage. Verify the gage against its Certificate of Accuracy before placing it into service, and re-calibrate on a schedule consistent with your quality management system requirements.
