Vermont Gage 111279100 Class Zz Minus Plug Pin Gage 0.7910 in

Product Description

The VERMONT GAGE 111279100 is a Class ZZ minus plug pin gage machined to a 0.7910-inch diameter, designed for NoGo inspection in dimensional quality control applications. Built from steel with a 10 micro-inch finish, it delivers a tolerance of 0.0002 inches, making it suitable for verifying that a feature does not accept an oversized condition. Each gage ships with a Certificate of Accuracy with NIST traceability, confirming calibration standards for shop floor and laboratory use. Metrology technicians, machinists, and quality inspectors use this tool to maintain consistent go/nogo workflows on production and inspection benches.

This pin gage is used in dimensional inspection setups where strict tolerance verification is required. Common applications include NoGo checks during in-process inspection, as well as calibration and verification of micrometers, verniers, and other precision measuring devices. The 2-inch overall length fits standard gage handle systems for handheld use at inspection stations. It is well suited for precision manufacturing environments in aerospace, automotive, and general machining where traceability to national standards is a documented requirement.

Key Features

• Class ZZ minus tolerance of 0.0002 inches for NoGo inspection applications
• 0.7910-inch diameter with 10 micro-inch surface finish for consistent seating
• 2-inch overall length compatible with standard gage handle systems
• Steel construction provides durability under regular shop-floor use
• Includes Certificate of Accuracy with NIST traceability for auditable calibration records
• Suitable for setting and verifying micrometers, verniers, and other measuring devices

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for setting micrometers, verniers, and other precision measuring devices. Fits standard pin gage handles sized for the 0.7910-inch diameter range.

Installation Notes

This gage is handled by metrology technicians and quality inspectors — no power tools or utilities need to be shut down before use. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Do not force the pin into a feature; apply only light, consistent hand pressure to avoid false readings or gage wear. Store in the provided case or a protective sleeve away from temperature extremes to maintain calibration integrity.
