Vermont Gage 112214540 Class Zz Minus Plug Pin Gage 14.54mm

Product Description

The VERMONT GAGE 112214540 is a Class ZZ Minus plug pin gage used to perform NoGo inspection of bored, drilled, and reamed holes. It measures a nominal diameter of 14.54 mm with a tolerance of 0.00508 mm, making it suitable for precision dimensional verification in manufacturing and quality control environments. The steel construction provides durability for repeated use in shop-floor and inspection-room applications. Each unit ships with a Certificate of Accuracy with NIST traceability, supporting documented quality systems and audit requirements. This gage is installed and used by machinists, quality technicians, and metrology professionals.

This plug pin gage is intended for NoGo inspection applications where a hole must be confirmed to not exceed its maximum allowable diameter. It is also suited for setting and verifying micrometers, verniers, and other measuring devices requiring a traceable reference standard. Typical use is in precision machining, toolroom inspection, and quality assurance workflows in both job-shop and production environments where tight dimensional tolerances are maintained.

Key Features

Compatibility

Designed for use in NoGo hole inspection and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a traceable 14.54 mm diameter reference.

Installation Notes

Plug pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Apply a light film of instrument oil when storing to protect the ground surface. Do not force the gage into a hole; correct usage requires light hand pressure only. Periodic cleaning and calibration verification against the included NIST-traceable certificate are recommended to maintain accuracy.
