Vermont Gage 112316450 Class Zz Plus Plug Gage 16.45mm

Product Description

The VERMONT GAGE 112316450 is a Class ZZ Plus cylindrical plug gage used for dimensional go inspection of bored, reamed, or machined holes with a nominal diameter of 16.45 mm. Manufactured from tool steel with a 10 micro finish coating, this gage delivers a tolerance of 0.005 mm, making it suitable for precision quality control work in machine shops, production environments, and metrology labs. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO and AS quality systems. Overall length is 2.0000 inches. Licensed metrologists, quality technicians, and CNC machinists are the primary users of this gage type.

This plug gage is applied in go inspection routines to verify that a hole falls within its specified minimum material condition. It is commonly paired with set micrometers, verniers, and other precision measuring devices for calibration and verification workflows. Typical deployment covers precision machined components in aerospace, automotive, and general manufacturing where tight hole tolerances must be confirmed before assembly. The ASME B89.1 standard governs its dimensional and tolerance specifications, providing a recognized benchmark for dimensional gaging in North American manufacturing environments.

Compatibility

Designed for go inspection of holes with a nominal diameter of 16.45 mm. Intended for use with set micrometers, verniers, and other precision measuring devices as noted in the product application data.

Installation Notes

Plug gages are handled and applied by quality technicians and machinists — no power tools or mechanical fastening is required. Clean the gage and the hole being inspected before use to prevent debris from causing false readings or surface damage. Store the gage in its protective case when not in use to preserve the ground surface finish and prevent corrosion. Follow your facility calibration schedule and handle with clean, dry hands or cotton gloves to avoid introducing measurement error from thermal expansion or surface contamination.
