Vermont Gage 112417930 Class Zz Minus Plug Pin Gage 17.93mm

Product Description

The VERMONT GAGE 112417930 is a Class ZZ minus plug pin gage machined from steel and used to verify bore and hole dimensions in precision inspection work. This gage checks the NoGo limit of a tolerance band, confirming that a hole has not been machined undersize. At 17.93 mm in diameter with a tolerance of 0.00508 mm, it delivers the dimensional accuracy required for setting micrometers, verniers, and other calibrated measuring devices. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Metrology technicians, quality inspectors, and toolroom machinists are the primary users of this gage type.

This plug pin gage is suited for dimensional inspection in manufacturing, toolroom, and quality-control environments. It is used in applications where bore acceptance or rejection must be confirmed against tight tolerances. Common uses include incoming inspection of machined parts, setup verification for precision measurement instruments, and calibration support tasks. The 17.93 mm diameter targets metric bore applications in both production and laboratory settings. Overall length is 2 inches, making it compatible with standard gage-handle systems.

Key Features

• Class ZZ minus tolerance specification for NoGo inspection applications
• 17.93 mm diameter with a 0.00508 mm tolerance for high-precision fit verification
• Steel construction for durability and dimensional stability under repeated use
• 10 micro coating and finish for surface consistency and corrosion resistance
• Includes Certificate of Accuracy with NIST traceability for documentation and calibration records
• 2-inch overall length compatible with standard plug gage handles

Compatibility

Designed for use with standard plug gage handles and compatible with micrometers, verniers, and other precision measuring devices requiring a calibrated reference for setup and NoGo inspection of metric bores.

Installation Notes

Plug pin gages are handled and used by metrology technicians and quality inspectors - no installation in the traditional sense applies. Store the gage in its protective case when not in use to prevent surface damage. Never force the gage into a bore; apply only light hand pressure. Clean contact surfaces before each use and re-verify calibration status according to your facility's gage-control procedure.
