Vermont Gage 111173200 Class Zz Plus Plug Gage 0.732 in

Product Description

The VERMONT GAGE 111173200 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored holes, machined bores, and other cylindrical features. It measures a nominal diameter of 0.732 inches with a tolerance of 0.0002 inches and a 10 microinch surface finish, providing reliable Go inspection performance in production and quality-control environments. The gage is machined from tool steel for wear resistance and dimensional stability. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements in regulated inspection programs. Machinists, quality technicians, and tool-and-die professionals install and use this gage as part of a calibrated gaging system.

This plug gage is suited for Go inspection tasks in manufacturing, job-shop, and metrology-lab settings. It is used to verify that a bored or reamed hole has been machined to the correct minimum accepted size before assembly. The 111173200 is also referenced when setting micrometers, verniers, and other measuring devices to a known standard, making it a dual-purpose reference standard in shops that require traceable dimensional verification. It is appropriate for both light production-floor use and bench inspection workflows.

Key Features

• 0.0002 inch tolerance per Class ZZ Plus classification
• 10 microinch surface finish for accurate seating and repeatable readings
• Tool steel construction provides hardness and long service life
• Certificate of Accuracy with NIST traceability included
• Meets ASME B89.1 standard

Compatibility

Designed for use as a Go inspection gage and as a setting reference for micrometers, verniers, and other measuring devices in standard bore-inspection applications.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent corrosion and surface damage. Clean the gage and the workpiece bore with a lint-free cloth before use to ensure accurate seating. Do not force the gage into an undersized bore, as this will damage the gage surface and invalidate calibration.
