Vermont Gage 911219100 Class Zz Minus Plug Pin Gage 0.1910 in

Product Description

The VERMONT GAGE 911219100 is a Class ZZ Minus plug pin gage machined to a nominal diameter of 0.1910 inches with a tolerance of 0.0002 inches. It is used to verify that a hole or bore does not exceed its maximum allowable size, functioning as a NoGo member in go/no-go inspection routines. The gage is manufactured from steel with a black oxide finish that resists corrosion and reduces light reflection during use. Each unit ships with a Certificate of Accuracy that carries NIST traceability, supporting quality management and audit requirements in precision manufacturing environments.

This pin gage is suited for dimensional inspection in machine shops, tool rooms, and manufacturing facilities where bore and hole acceptance criteria must be validated to tight tolerances. It is compatible with set micrometers, verniers, and other measuring devices as a reference standard. The 2-inch overall length provides adequate handling clearance for most bench and inline inspection setups. Machinists, quality technicians, and calibration professionals are the primary users of this type of gage.

Key Features

• Class ZZ Minus tolerance class — 0.0002 inches — for NoGo inspection applications
• Nominal diameter of 0.1910 inches for precise bore and hole verification
• Steel construction with black oxide finish for corrosion resistance and reduced glare
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• 2-inch overall length suits standard bench inspection and inline gauging setups
• Compatible with set micrometers, verniers, and other reference measuring devices

Compatibility

Designed for use as a NoGo inspection gage and as a setting reference for set micrometers, verniers, and other measuring devices where a 0.1910-inch diameter pin standard is required.

Installation Notes

Handle pin gages with clean cotton or nitrile gloves to prevent skin oils from affecting surface finish and measurement accuracy. Store the gage in its protective case when not in use to prevent nicking or scratching the gage surface. Verify the gage is at thermal equilibrium with the workpiece before use, as temperature differentials can introduce dimensional error. Periodic recalibration against a NIST-traceable standard is recommended to maintain accuracy over time.
