Vermont Gage 112205400 Class Zz Minus Plug Pin Gage 5.40mm

Product Description

The VERMONT GAGE 112205400 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection of precision bored holes and internal features. It checks whether a hole or bore has been cut too large by confirming the gage does not pass through the workpiece at the upper tolerance limit. The gage measures a nominal diameter of 5.40 mm with a tolerance of 0.00508 mm, giving inspectors and machinists a reliable, traceable reference for tight-tolerance work. Each unit ships with a Certificate of Accuracy that includes NIST traceability, supporting audit and calibration records.

This pin gage is suited for use in machine shops, toolrooms, and quality control environments where hole diameter verification is required on machined components. It is also appropriate for setting and checking micrometers, verniers, and other measuring devices that require a known reference dimension. At 2 inches overall length, it fits comfortably in standard gage blocks, gage holders, or hand use. The 10 microfinish surface coating helps maintain consistent contact and reduces wear during repeated inspection cycles.

Key Features

• Compact 2-inch overall length compatible with standard gage holders and hand use

Compatibility

Designed for use in NoGo hole inspection, and for setting micrometers, verniers, and other precision measuring devices requiring a 5.40 mm reference diameter.

Installation Notes

Pin gages are handled and used by machinists, quality technicians, and metrologists - no installation in the mechanical sense is required. Store the gage in its case when not in use to prevent surface damage and corrosion. Clean contact surfaces with a lint-free cloth before each use to maintain measurement accuracy. Avoid dropping or striking the gage, as impact can alter the precision ground diameter and void traceability.
