Vermont Gage 111208900 Class Zz Minus Plug Pin Gage 0.089 in

Product Description

The VERMONT GAGE 111208900 is a Class ZZ minus tolerance plug pin gage used to verify that a hole or bore does not exceed its maximum allowable size. Measuring 0.0890 inches in diameter with an overall length of 2 inches, this pin gage is machined from steel and finished to a 10 microfinish surface. The minus tolerance designation means the gage pin is manufactured below the nominal diameter, making it suitable for NoGo inspection applications. Each unit ships with a Certificate of Accuracy backed by NIST traceability, supporting documentation requirements in calibrated inspection environments. Dimensional tolerance is held to 0.0002 inches.

This pin gage is intended for use in precision inspection tasks where a NoGo member is needed to confirm hole diameter does not exceed specification. Typical applications include incoming and in-process quality control in machine shops, toolrooms, and manufacturing facilities. It is also compatible for use with setting micrometers, verniers, and other comparative or direct measuring devices that require a known reference diameter. The 0.0890-inch size suits small-bore work common in close-tolerance mechanical assembly and precision fabrication.

Key Features

• Class ZZ minus tolerance for NoGo inspection of small-bore holes and features
• 0.0890-inch diameter held to a tolerance of plus or minus 0.0002 inches
• 10 microfinish surface coating for accurate, repeatable contact measurement
• Steel construction for durability in production inspection environments
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• 2-inch overall length for easy handling and gauge block or fixture use

Compatibility

Designed for NoGo inspection use and compatible with setting micrometers, verniers, and other measuring devices requiring a precision reference pin at 0.0890 inches diameter.

Installation Notes

Pin gages are handled and used by quality technicians, machinists, and metrology personnel. Before use, clean the gage and the bore being checked to remove chips, oil, and debris that could affect readings. Do not force the pin into a hole; apply only light hand pressure to avoid damage to the gage or the workpiece. Store pin gages in a protective case away from temperature extremes to maintain dimensional stability and preserve the certificate of accuracy.
