Vermont Gage 112316470 Class Zz Plus Plug Gage 16.47mm

Product Description

The VERMONT GAGE 112316470 is a Class ZZ Plus plug gage designed for precision dimensional inspection of cylindrical bores and holes. Machined from tool steel with a 10 micro finish, this gage checks a nominal diameter of 16.47 mm with a tolerance of 0.00508 mm, making it suitable for go inspection applications where tight dimensional control is required. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. Machinists, quality technicians, and metrologists rely on this type of gage for fast, repeatable pass/fail verification on the shop floor or in the inspection lab.

This plug gage is used in go inspection routines to verify that a bored, drilled, or reamed hole meets minimum size requirements before a part advances to assembly or final inspection. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a traceable reference standard. With an overall length of 2.0000 inches, it is compact enough for bench inspection work across light manufacturing, toolroom, and quality assurance environments in both production and job shop settings.

Key Features

• Class ZZ Plus tolerance class: 0.00508 mm tolerance for precise go inspection
• 16.47 mm nominal diameter with 10 micro surface finish for consistent gage contact
• Tool steel construction for durability and wear resistance in production environments
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for audit and calibration records
• Compact 2.0000-inch overall length suitable for bench and floor inspection use

Compatibility

Suitable for use as a go plug gage reference in bore inspection applications and for setting micrometers, verniers, and other measuring devices requiring a traceable dimensional standard at 16.47 mm.

Installation Notes

Plug gages are handled and used by quality technicians and machinists trained in precision measurement practices. Store the gage in its case when not in use to protect the lapped surface from damage and contamination. Clean the gage and the workpiece bore before use to prevent debris from causing false readings or accelerated wear. Do not force the gage into undersize holes, as this damages the gage surface and compromises measurement accuracy.
