Vermont Gage 112404110 Class Zz Minus Plug Pin Gage 4.11mm

Product Description

The VERMONT GAGE 112404110 is a Class ZZ minus plug pin gage designed for dimensional inspection work in metrology and quality control environments. It measures a nominal diameter of 4.11 mm with a tolerance of 0.00508 mm, providing the close control required for NoGo inspection applications. Machined from steel and finished to a 10 microfinish surface, it delivers the consistency and wear resistance that precision inspection demands. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for use in calibrated inspection programs and traceable quality systems.

This plug gage is intended for NoGo inspection use, confirming that a hole or bore does not exceed its maximum allowable size. It is also applicable for setting and checking micrometers, verniers, and other measuring devices requiring a certified reference standard. At 2 inches overall length, the gage fits comfortably in hand-held inspection use across light manufacturing, machine shops, and quality labs handling small-bore workpieces in the 4 mm diameter range.

Compatibility

Designed for use in NoGo bore inspection applications and as a setting reference for micrometers, verniers, and other precision measuring devices requiring a certified plug gage standard in the 4 mm diameter range.

Installation Notes

Plug pin gages are handled and used by quality technicians and metrologists in inspection environments. 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. Store in a protective case away from abrasive materials to preserve the 10 microfinish surface and maintain calibration integrity.
