Vermont Gage 112201840 Class Zz Minus Plug Pin Gage 1.84mm

Product Description

The VERMONT GAGE 112201840 is a Class ZZ Minus plug pin gage machined from steel and used to verify bore and hole dimensions in precision inspection applications. With a measurement diameter of 1.84 mm and a tolerance of 0.00508 mm, this gage delivers the dimensional accuracy required for NoGo inspection work. The 10 Microfinish surface coating ensures consistent contact and reliable readings across repeated use. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for calibrated inspection environments. Licensed metrology technicians and quality control professionals install and use this tool in shop-floor and lab settings.

This plug pin gage is sized for NoGo inspection of 1.84 mm diameter features. It is also used to calibrate and verify the accuracy of micrometers, verniers, and other measuring devices. The 2-inch overall length provides a comfortable grip for single-handed operation during routine inspection tasks. This type of gage is common in precision manufacturing, machining, and quality assurance workflows where hole tolerances must be held to tight standards.

Key Features

• Steel construction for durability under regular shop-floor use
• Includes Certificate of Accuracy with NIST traceability for calibrated inspection use
• Designed for use with micrometers, verniers, and other precision measuring devices

Compatibility

Designed as an OEM-style plug pin gage for NoGo inspection of 1.84 mm diameter bores, and for use as a reference standard with micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug pin gages are handled and used by metrology technicians and quality control personnel. Store the gage in its protective case when not in use to prevent nicks or surface damage that could affect dimensional accuracy. Clean the gage and the bore being checked before use to prevent contamination from affecting readings. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece surface.
