Vermont Gage 111162600 Class Zz Plus Plug Gage 0.626in

Product Description

The VERMONT GAGE 111162600 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored, reamed, and drilled holes. It measures a nominal diameter of 0.626 inches with a tolerance of 0.0002 inches and a 10 microinch surface finish. Manufactured from tool steel, this gage delivers the hardness and wear resistance required for repetitive inspection work. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Dimensional inspection technicians, machinists, and quality control personnel use this gage to verify hole sizes against engineering tolerances in production and metrology environments.

This plug gage is suited for go inspection tasks across manufacturing, job shop, and quality lab settings. It is used to verify that a hole meets the minimum acceptable diameter before a part advances in production. Typical applications include checking holes sized for press fits, clearance fits, and locating features. It is also used as a reference standard when setting micrometers, verniers, and other variable measuring instruments. The 2.0-inch overall length provides a practical handle length for single-hand operation during bench or in-process inspection.

Key Features

• 0.626-inch nominal diameter with 0.0002-inch tolerance for tight conformance checking
• 10 microinch surface finish for repeatable, low-wear contact with the workpiece bore
• Tool steel construction for durability and dimensional stability under repeated use
• Includes Certificate of Accuracy with NIST traceability
• Manufactured to ASME B89.1 dimensional standards
• 2.0-inch overall length for practical single-hand operation

Compatibility

Designed as a go inspection plug gage for use with bored or drilled holes at 0.626 inches nominal diameter. Also suitable as a setting reference for micrometers, verniers, and other calibrated measuring devices.

Installation Notes

Plug gages should be handled by qualified inspection personnel or machinists following established gage-handling procedures. Clean the gage and the hole to be inspected before use to prevent debris from affecting readings or damaging the gage surface. Do not force the gage into a hole; excessive insertion force can damage the gage or the workpiece and will produce invalid results. Store the gage in its case when not in use to protect the lapped surface finish.
