Vermont Gage 111427650 Class Zz Minus Plug Pin Gage 0.2765 in

Product Description

The VERMONT GAGE 111427650 is a Class ZZ minus plug pin gage machined from steel and used to perform NoGo inspection checks on bored holes, drilled passages, and machined features. It measures 0.2765 inches in diameter with a tolerance of 0.0002 inches, making it suitable for dimensional verification work where tight tolerance confirmation is required. Each gage ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements of most quality management systems. Overall length is 2 inches, and the surface is finished to a 10 microfinish for consistent, repeatable contact. Machinists, toolmakers, and quality technicians are the primary users of this type of gage.

Class ZZ minus plug gages are used in production inspection and metrology applications where a NoGo member is needed to confirm a feature does not exceed its maximum material condition. This gage is also appropriate for setting and verifying micrometers, verniers, and other measuring devices requiring a traceable reference standard. It is well suited to machine shops, manufacturing floors, and quality labs handling precision components in residential, commercial, or industrial production environments.

Key Features

• Steel construction with 10 microfinish surface for consistent contact and long service life
• Certificate of Accuracy with NIST traceability included for quality system compliance
• 2 inch overall length provides comfortable handling and adequate reach for standard applications
• Compatible with micrometers, verniers, and other precision measuring devices as a reference standard

Compatibility

Designed for NoGo inspection use and for setting or verifying micrometers, verniers, and other precision measuring devices requiring a traceable dimensional reference.

Installation Notes

Plug pin gages are handled and used by machinists, toolmakers, and quality inspection personnel rather than installed in a system. 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; a NoGo member should not enter a correctly sized hole. Store in the original protective sleeve or case to maintain the calibrated surface finish.
