Vermont Gage 112111860 Class Zz Plus Plug Gage 11.86 Mm

Product Description

The VERMONT GAGE 112111860 is a Class ZZ Plus plug gage used to verify bore and hole diameters to tight dimensional tolerances. It measures a nominal diameter of 11.86 mm with a tolerance of 0.00508 mm, making it suitable for go inspection applications where precise dimensional conformance is required. Manufactured from tool steel with a 10 microfinish surface coating, the gage maintains dimensional stability under repeated use. At 2.0000 inches overall length and 0.1 pounds, it is designed for bench and in-process inspection tasks. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming compliance with ASME B89.1 standards.

This plug gage is used in quality control and metrology environments where hole or bore diameters must be validated to go inspection criteria. Typical applications include setting and verifying micrometers, verniers, and other measuring devices, as well as in-process part inspection in machining and manufacturing. It is appropriate for use in tool rooms, production floors, and calibration labs where dimensional accuracy is critical. Machinists, quality technicians, and metrologists are the primary users of this type of gage.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists during inspection procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; apply light, consistent hand pressure only to avoid damage to the gage or the workpiece. Store in a protective case away from heat sources and abrasive materials to preserve surface finish and calibration integrity.
