Vermont Gage 112113400 Class Zz Plus Plug Gage 13.4 Mm

Product Description

The VERMONT GAGE 112113400 is a Class ZZ Plus cylindrical plug gage designed to verify bore diameters to a nominal size of 13.4 mm. Manufactured from tool steel with a 10 microfinish surface, it delivers a tolerance of 0.00508 mm, meeting ASME B89.1 standards. Each unit ships with a Certificate of Accuracy traceable to NIST, making it a reliable choice for quality-control workflows in machine shops, toolrooms, and production environments. Dimensional inspectors, machinists, and metrology technicians use this type of plug gage as a fast, repeatable go-inspection tool.

This plug gage is suited for go inspection of machined bores, drilled holes, and reamed features where tight diameter tolerances must be verified. It is also used as a reference standard when setting micrometers, verniers, bore gages, and other measuring devices to a known 13.4 mm dimension. The overall length of 2.0000 inches allows comfortable single-hand use in both bench and in-process inspection settings. Typical applications span aerospace, automotive, and general precision manufacturing environments.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for precise go-inspection verification
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for smooth, consistent gaging contact
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• Compatible as a setting master for micrometers, verniers, and bore gages

Compatibility

Designed for go inspection of bores and holes with a nominal diameter of 13.4 mm. Also functions as a reference standard for setting micrometers, verniers, and other measuring devices to a known diameter.

Installation Notes

Plug gages are handled and used by dimensional inspectors and quality technicians — no power source or lockout procedure is required. Store the gage in its case when not in use to protect the gaged surface from nicks and contamination. Clean the bore and gage surfaces with a lint-free cloth before use to prevent debris from affecting the reading. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity over time.
