Vermont Gage 112309950 Class Zz Plus Plug Gage 9.95 Mm

Product Description

The VERMONT GAGE 112309950 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of bored holes and machined features. It measures a nominal diameter of 9.95 mm with a tolerance of 0.00508 mm, making it suitable for verifying close-tolerance work in production and quality-control environments. The gage body has a 10 microfinish surface, which supports consistent contact and repeatable readings. A Certificate of Accuracy with NIST traceability is included, satisfying documentation requirements for calibrated toolroom and inspection lab applications. Machinists, toolroom technicians, and quality inspectors are the primary users of this gage.

This plug gage is used in go inspection routines to confirm that a machined hole or bore meets minimum size requirements. It is also appropriate for setting and verifying micrometers, verniers, and other comparative measuring devices to a known reference diameter. Typical applications include in-process quality checks on CNC-machined parts, final inspection in tool rooms, and calibration reference work in metrology labs. The 2.00-inch overall length fits standard gage handle systems used in general production settings.

Compatibility

Designed for use in go inspection of machined holes and bores at 9.95 mm nominal diameter, and for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by machinists, toolroom technicians, and quality inspectors and do not require power tools or mechanical installation. Store the gage in its protective case when not in use to prevent surface damage and contamination. Clean mating surfaces and the gage body before use to avoid false readings caused by debris or burrs. Handle with clean cotton gloves or a lint-free cloth to prevent corrosion from skin contact.
