Vermont Gage 111226500 Class Zz Minus Plug Pin Gage 0.2650 in

Product Description

The VERMONT GAGE 111226500 is a Class ZZ Minus plug pin gage machined from steel and used for NoGo dimensional inspection work. With a measurement diameter of 0.2650 inches and an overall length of 2 inches, this pin gage delivers a tolerance of 0.0002 inches, making it suitable for verifying that a bore or hole does not exceed its maximum allowable size. The 10-microfinish surface coating supports accurate, repeatable contact with the workpiece. Every unit ships with a Certificate of Accuracy traceable to NIST standards, meeting the documentation requirements common in quality-controlled manufacturing and inspection environments.

This pin gage is intended for NoGo inspection applications, including use with set micrometers, verniers, and other precision measuring devices. It is commonly used on the shop floor or in inspection departments where bore size acceptance criteria must be verified to tight tolerances. The Class ZZ designation places it in the general-purpose inspection category, appropriate for production inspection rather than master gage or laboratory-grade applications. Licensed metrologists, quality technicians, and machining professionals are the primary users of this gage.

Key Features

• Class ZZ Minus tolerance class for NoGo inspection applications
• 0.2650-inch measurement diameter with 0.0002-inch tolerance
• Steel construction with 10-microfinish surface coating for consistent contact
• Certificate of Accuracy included with NIST traceability for quality documentation
• Compact 2-inch overall length suitable for benchtop and floor inspection use

Compatibility

Designed for use in NoGo bore inspection setups and compatible with set micrometers, verniers, and other precision measuring devices where a 0.2650-inch diameter plug gage is required.

Installation Notes

Pin gages are handled and used by quality technicians and inspection personnel rather than installed in the traditional sense. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel body. Never force a plug gage into a bore — apply only light, controlled hand pressure to avoid damaging the gage or the workpiece. Store in a protective case away from impact, heat sources, and abrasive materials to maintain calibration integrity.
