Vermont Gage 112206400 Class Zz Minus Plug Pin Gage 6.40mm

Product Description

The VERMONT GAGE 112206400 is a Class ZZ Minus plug pin gage designed for precise dimensional inspection of bored holes and machined features at 6.40 mm diameter. Built from steel with a 10 microfinish surface coating, this pin gage delivers a tolerance of 0.00508 mm, making it suitable for NoGo inspection work where tight conformance to dimensional limits is required. Each unit ships with a Certificate of Accuracy that includes NIST traceability, providing documented evidence for quality control and audit purposes. Overall length is 2 inches, and the unit weighs 0.03 pounds.

This plug pin gage is used in manufacturing, tooling, and quality assurance environments where go/nogo gauging of hole diameters is part of the inspection process. It is appropriate for use alongside set micrometers, verniers, and other calibrated measuring devices. Typical applications include incoming inspection, in-process checks on machined components, and final verification of bored or drilled features. It is handled by machinists, quality technicians, and metrologists working to tight dimensional tolerances in job shop and production settings.

Key Features

• Class ZZ Minus tolerance classification at 0.00508 mm for NoGo gauging applications
• 6.40 mm measurement diameter with 2-inch overall length
• Steel construction with 10 microfinish surface coating for dimensional stability and wear resistance
• Includes Certificate of Accuracy with NIST traceability for documentation and compliance
• Compatible for use with set micrometers, verniers, and other precision measuring instruments

Compatibility

Designed for NoGo inspection use with set micrometers, verniers, and other precision measuring devices requiring a 6.40 mm reference diameter.

Installation Notes

Pin gages are handled by quality technicians and machinists and require no installation in the traditional sense. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a feature; apply light, consistent hand pressure only to avoid damage to the gage or the workpiece. Store separately from other metal tools to protect the precision-ground surface.
