Vermont Gage 911215400 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 911215400 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection. It measures a nominal diameter of 0.1540 inches with a tolerance of 0.0002 inches, making it suitable for NoGo inspection applications where tight measurement accuracy is required. The gage is machined from steel with a black oxide finish for corrosion resistance and durability. It ships with a Certificate of Accuracy with NIST traceability, confirming it meets Class ZZ standards. Metrology technicians, quality control inspectors, and machinists use this type of gage for verifying hole diameters and calibrating measuring instruments.

This pin gage is intended for use in NoGo inspection routines, as well as for setting and verifying micrometers, verniers, and other precision measuring devices. It is commonly used in machine shops, manufacturing facilities, and quality labs where repeatable, traceable dimensional verification is required. The 2-inch overall length provides a standard handle grip suitable for use with conventional gage blocks and plug gage handles. Its compact size makes it practical for bench inspection and inline production checks.

Installation Notes

Pin gages should be handled by metrology personnel or quality technicians familiar with precision measurement practices. Store the gage in its protective case when not in use to prevent surface damage that could affect accuracy. Clean the gage and the reference surface before use to avoid measurement errors caused by debris or contamination. Do not force the gage into a hole; controlled insertion pressure is required to prevent damage to the gage or the workpiece.
