Vermont Gage 111316850 Class Zz Plus Plug Gage 0.1685 in

Product Description

The VERMONT GAGE 111316850 is a Class ZZ Plus plug gage designed to verify hole and bore diameters to a nominal size of 0.1685 inches. Machined from tool steel, it holds a tolerance of 0.0002 inches and features a 10 microfinish surface for consistent, repeatable contact. Overall length is 2.0 inches, making it compatible with standard gage handle setups. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1. Machinists, quality technicians, and tool-room personnel use this gage as part of a go-inspection routine or to calibrate and verify the accuracy of micrometers, verniers, and other measuring devices.

This plug gage is suited for use in manufacturing, tool-and-die, and quality-control environments where dimensional verification of small-diameter features is required. It is appropriate for both production floor inspection and bench-level calibration of measuring instruments. Typical applications include go inspection checks on drilled or reamed holes, and as a reference standard when setting micrometers or vernier calipers to a known diameter.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• Tool steel construction for durability and wear resistance
• 10 microfinish surface for consistent, repeatable gage contact
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• 2.0-inch overall length compatible with standard plug gage handles

Compatibility

Designed for use in go inspection of holes and bores at 0.1685 inches nominal diameter, and as a setting reference for micrometers, verniers, and other measuring devices. Compatible with standard plug gage handle assemblies sized for this diameter range.

Installation Notes

Plug gages should be handled and stored carefully to prevent surface damage that would affect accuracy. Clean the gage and the workpiece bore with a lint-free cloth before use to remove chips, oil, and debris. Apply only light hand pressure during inspection — never force the gage into a bore. Periodic recalibration against a certified reference standard is recommended to confirm continued accuracy.
