Vermont Gage 112101100 Class Zz Plus Plug Gage 1.1 Mm

Product Description

The VERMONT GAGE 112101100 is a Class ZZ Plus plug gage machined from tool steel and designed for precision bore and hole inspection in industrial and metrology environments. With a 1.1 mm diameter and a tolerance of 0.005 mm, this gage is used to verify whether a hole or bore meets its go inspection criteria. The 10 microfinish surface finish ensures repeatable, accurate contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrologists use this class of gage in production and inspection settings where tight dimensional control is required.

This plug gage is suited for go inspection applications where confirming minimum acceptable hole size is critical. It is also used to set and verify micrometers, verniers, and other measuring devices. The 1.1 mm diameter targets small-bore inspection work common in precision machining, medical device manufacturing, electronics, and similar industries where sub-millimeter tolerances are routine. The overall length of 2.0000 inches accommodates standard gage handle use, though the gage may also be used directly depending on the application setup.

Key Features

• 10 microfinish surface finish for consistent, repeatable gage contact
• Tool steel construction provides hardness and long service life
• Includes Certificate of Accuracy with NIST Traceability
• Conforms to ASME B89.1 dimensional metrology standards
• Suitable for setting micrometers, verniers, and other measuring instruments

Compatibility

Designed for go inspection of 1.1 mm diameter bores and holes; also compatible for use in setting micrometers, verniers, and other measuring devices as stated by the manufacturer.

Installation Notes

This gage is handled by quality technicians and machinists — no power source or electrical shutoff is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; excessive insertion force can damage the gage or the workpiece. Store in the provided case or a protective sleeve to maintain the 10 microfinish surface condition.
