Vermont Gage 112310870 Class Zz Plus Plug Gage 10.87 Mm

Product Description

The VERMONT GAGE 112310870 is a Class ZZ Plus plug gage designed for precise bore and hole inspection in dimensional metrology applications. Manufactured from tool steel with a 10 microfinish surface coating, this plug gage measures 10.87 mm in diameter with a tolerance of 0.00508 mm. The overall length is 2.0000 inches. It ships with a Certificate of Accuracy traceable to NIST, making it suitable for calibration-controlled environments. Dimensional inspection technicians and quality control professionals use this gage to verify hole sizes against Go inspection criteria in accordance with ASME B89.1 standards.

This plug gage is used in Go inspection applications for verifying the minimum acceptable size of bored, drilled, or reamed holes. It is compatible with use alongside set micrometers, verniers, and other measuring devices as a reference or verification standard. Typical deployment is in machine shops, manufacturing quality labs, and calibration departments where tight dimensional tolerances must be confirmed before assemblies proceed. The Class ZZ Plus designation indicates a tighter tolerance grade suitable for precision inspection work.

Compatibility

Designed for use with set micrometers, verniers, and other measuring devices in Go inspection applications per ASME B89.1. Compatible with standard plug gage handle systems sized for 10.87 mm gage members.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and measurement error from skin oils. Before use, verify the gage and workpiece are at the same ambient temperature, ideally 68 degrees F (20 degrees C), to eliminate thermal expansion error. Never force a plug gage into an undersized hole; apply only light, consistent hand pressure. Store the gage in its protective case when not in use and inspect for wear or damage before each calibration cycle.
