Vermont Gage 111136900 Class Zz Plus Plug Gage 0.369 in

Product Description

The VERMONT GAGE 111136900 is a Class ZZ Plus plug gage designed for dimensional inspection of bored holes, reamed holes, and other cylindrical features. It measures 0.369 inches in diameter with a tolerance of 0.0002 inches and features a 10 microfinish surface on the gaging member. The overall length is 2.0 inches. Manufactured from tool steel, this gage is built to withstand repeated use in production and quality-control environments. A Certificate of Accuracy with NIST traceability is included, supporting documentation requirements for ISO and AS9100 quality systems. This gage is handled and used by machinists, quality technicians, and metrology professionals.

This plug gage is suited for go inspection applications in machine shops, tool rooms, and manufacturing facilities. It is used to verify that a hole has been produced within the minimum acceptable size, confirming that a mating part or fastener will pass through. It is also commonly used to set and verify micrometers, verniers, and other measuring devices requiring a known reference. The Class ZZ Plus designation indicates compliance with ASME B89.1 tolerance standards for plug gages, making it appropriate for both production floor checks and calibration lab use.

Installation Notes

Plug gages are handled by quality technicians and metrology personnel and do not require power-down procedures. Store gages in a protective case away from moisture to prevent corrosion of the tool steel surface. Apply a light film of instrument oil when gages are not in use for extended periods. Handle with clean, dry hands or lint-free gloves to prevent surface contamination that can affect measurement accuracy.
