Vermont Gage 112314430 Class Zz Plus Plug Gage 14.43mm

Product Description

The VERMONT GAGE 112314430 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of bored, reamed, or otherwise finished holes. It checks whether a hole falls within acceptable size limits before parts move to the next stage of production or assembly. The gage measures a nominal diameter of 14.43 mm with a tolerance of 0.005 mm (0.00508 mm precise), and carries an overall length of 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented quality systems and audit requirements. Manufactured to ASME B89.1 standards, this gage is suited for use in precision metrology environments alongside micrometers, verniers, and other calibrated measuring devices.

This plug gage is used in machine shops, fabrication facilities, and quality control labs where hole diameter verification is required. It is appropriate for go inspection tasks on production runs where consistent bore size is critical. The 14.43 mm diameter targets applications in general mechanical assembly, tooling, and component inspection. Its compatibility with standard gage handle systems and its compact size make it practical for both bench inspection and in-process checks on the shop floor. Licensed metrology technicians and quality control inspectors are the primary users of this tool.

Compatibility

Designed for use with standard plug gage handle systems and suitable for go inspection setups using micrometers, verniers, and other calibrated measuring devices per ASME B89.1 applications.

Installation Notes

This gage is handled and used by metrology technicians and quality control inspectors. Before use, clean the gage and the bore to remove chips, coolant, and debris that could affect readings. Apply light gage oil when appropriate to protect the tool steel surface and extend service life. Do not force the gage through an undersized hole, as this will damage the gage surface and invalidate calibration; always re-verify calibration per your facility schedule.
