Vermont Gage 911105500 Class Zz Plus Plug Gage 0.055 in

Product Description

The VERMONT GAGE 911105500 is a Class ZZ Plus plug gage used to inspect bore and hole dimensions with precision tolerance verification. Built from tool steel with a black oxide finish, this gage measures a nominal diameter of 0.055 inches and holds a tolerance of 0.0002 inches. It has an overall length of 2.0 inches. Inspection technicians, machinists, and quality control personnel use this gage to verify go-condition fits in production and receiving inspection settings. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming conformance to ASME B89.1 standards.

This plug gage is suited for use in machine shops, manufacturing facilities, and metrology labs where precise hole diameter verification is required. Applications include go inspection checks and calibration or verification of micrometers, verniers, and other measuring devices. Its compact size and durable black oxide finish make it practical for both bench and floor-level inspection use in light and heavy manufacturing environments.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Avoid dropping or storing in contact with abrasive surfaces, as impact or scoring will affect measurement accuracy. Verify calibration status before use in critical inspection applications.
