Vermont Gage 112101660 Class Zz Plus Plug Gage 1.66mm

Product Description

The VERMONT GAGE 112101660 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes. Machined from tool steel, this plug gage measures a nominal diameter of 1.66 mm with a tolerance of 0.00508 mm, delivering the accuracy required for go inspection applications. The 10 microfinish surface finish ensures consistent, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for use in calibrated inspection environments. Metrology technicians, quality control personnel, and tool room machinists are the primary users of this gage.

This plug gage is used in go inspection routines to verify that a bore or hole meets its minimum acceptable diameter. It is appropriate for use alongside set micrometers, verniers, and other precision measuring devices as a reference or check standard. The 1.66 mm diameter makes it well suited for small-bore inspection tasks common in precision machined parts manufacturing, medical component production, and tight-tolerance assembly operations. The overall length of 2.0000 inches provides sufficient handling clearance for bench and fixture use.

Key Features

• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0000 inches for standard bench handling

Compatibility

Designed for use in go inspection applications and as a reference standard with set micrometers, verniers, and other precision measuring devices per the manufacturer specification.

Installation Notes

Plug gages are handled and used by metrology or quality control personnel and do not require mechanical installation. Store the gage in its protective case when not in use to prevent damage to the finished surface. Clean contact surfaces with a lint-free cloth before each use to ensure accurate readings. Calibration intervals should be established per your facility quality system in accordance with ASME B89.1.
