Vermont Gage 112102140 Class Zz Plus Plug Gage 2.14mm

Product Description

The VERMONT GAGE 112102140 is a Class ZZ Plus cylindrical plug gage designed for precision dimensional inspection of small bores and holes. Built from tool steel with a 10 microfinish surface, it provides reliable go-type inspection at a 2.14 mm diameter with a tolerance of 0.00508 mm. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming compliance with ASME B89.1 dimensional standards. This gage is intended for use by quality technicians, machinists, and metrology personnel performing in-process or final inspection on the shop floor or in a calibration lab.

This plug gage is suited for go inspection applications where tight dimensional verification of small internal diameters is required. It is also compatible with setup and calibration of micrometers, verniers, and other measuring devices. Typical installation scenarios include incoming inspection, in-process quality checks, and gauge room verification routines in manufacturing, aerospace, automotive, and general machining environments. The compact overall length of 2.0 inches makes it practical for use in benchtop inspection fixtures and hand-held measurement setups.

Key Features

• Class ZZ Plus tolerance grade: 0.00508 mm tolerance for high-accuracy go inspection
• 2.14 mm nominal diameter in tool steel construction for durability and wear resistance
• 10 microfinish surface for consistent, repeatable contact with bore surfaces
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards for dimensional gaging
• Compatible with micrometers, verniers, and other precision measuring devices for setup and calibration

Compatibility

Designed for go inspection of 2.14 mm diameter bores and for setting micrometers, verniers, and other measuring devices requiring a precise reference standard.

Installation Notes

Plug gages should be handled by qualified metrology or quality personnel. Clean the gage and bore thoroughly before use to avoid false readings caused by debris or surface contamination. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain dimensional integrity and NIST-traceable accuracy.
