Vermont Gage 112406550 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 112406550 is a Class ZZ Minus plug pin gage manufactured from steel for dimensional inspection work. It measures a nominal diameter of 6.55 mm with a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where precise bore verification is required. The gage has an overall length of 2 inches and features a 10 microfinish surface coating for accurate, repeatable contact with the workpiece. A Certificate of Accuracy with NIST Traceability is included, supporting quality documentation requirements in calibration and inspection environments.

This pin gage is used in metrology and quality control settings for verifying bore and hole diameters in manufactured parts. The NoGo designation means it is applied to confirm that a bore has not been machined oversized beyond the specified tolerance limit. It is commonly used alongside set micrometers, verniers, and other precision measuring devices in manufacturing inspection, machine shop QC, and calibration lab workflows.

Installation Notes

Pin gages are handled and applied by quality control technicians, calibration specialists, and machinists. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a bore; apply light, consistent hand pressure only to avoid measurement error or surface damage. Store in a protective case away from abrasive materials and temperature extremes to maintain calibration integrity.
