Vermont Gage 112313030 Class Zz Plus Plug Gage 13.03mm

Product Description

The VERMONT GAGE 112313030 is a Class ZZ Plus cylindrical plug gage designed to verify bore diameters to tight dimensional tolerances. Manufactured from tool steel with a 10 microfinish surface, this plug gage measures 13.03 mm in diameter and carries a tolerance of 0.00508 mm. With an overall length of 2.0000 inches, it is built for repeatable go-inspection tasks on the shop floor or in a quality-control lab. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming compliance with ASME B89.1 dimensional standards. Machinists, quality technicians, and toolroom professionals rely on this type of gage for fast, reliable bore verification.

This plug gage is suited for go inspection of bored, reamed, or drilled holes in production and inspection environments. It works alongside set micrometers, verniers, and other precision measuring devices to confirm that machined features fall within specified tolerances. Typical applications include incoming inspection, in-process quality checks, and final part acceptance across metalworking, aerospace, and general manufacturing settings where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus tolerance rating with 0.00508 mm tolerance for tight bore verification
• 13.03 mm diameter for direct go-inspection use
• Tool steel construction for durability and wear resistance in production environments
• 10 microfinish surface for consistent, repeatable contact with bore walls
• Includes Certificate of Accuracy with NIST traceability
• Manufactured to ASME B89.1 standards

Compatibility

Designed for use as a go plug gage in standard bore inspection applications; compatible with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists in inspection settings. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; go gages should pass through a conforming hole with hand pressure only. Store in a protective case away from temperature extremes to maintain dimensional stability and NIST-traceable calibration integrity.
