Vermont Gage 112200520 Class Zz Plug Pin Gage 0.52 Mm

Product Description

The VERMONT GAGE 112200520 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection of small-diameter bores and holes. This pin gage measures 0.52 mm in diameter and carries a tolerance of 0.00508 mm, making it appropriate for NoGo inspection applications where tight tolerances are critical. The steel construction with a 10 microfinish surface coating ensures consistent, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy that includes NIST traceability, supporting documented quality control processes in production and metrology environments. Machinists, quality inspectors, and tool-room technicians are the primary users of this type of gage.

This pin gage is suited for use in precision manufacturing environments where bore diameter verification is required at the 0.52 mm size range. It is commonly used alongside set micrometers, verniers, and other calibrated measuring devices for NoGo go/no-go inspection routines. At 2 inches in overall length, the gage provides sufficient handling clearance for bench inspection work. Applications include incoming inspection, in-process quality checks, and calibration support tasks across aerospace, medical device, and general machining operations.

Compatibility

Designed for use with set micrometers, verniers, and other precision measuring devices requiring a 0.52 mm NoGo reference pin gage in Class ZZ Minus tolerance classification.

Installation Notes

Pin gages should be handled with clean cotton gloves to prevent oil and contamination from affecting measurement accuracy. Store the gage in its protective case when not in use to avoid surface damage. Verify the gage against a calibrated reference standard at regular intervals per your facility quality plan. No tools or power sources are required for use; inspect the gage visually for burrs or surface damage before each use.
