Vermont Gage 911102600 Class Zz Plus Plug Gage 0.026 in

Product Description

The VERMONT GAGE 911102600 is a Class ZZ Plus plug gage designed for precise go inspection of small-diameter bores and holes. Manufactured from tool steel with a black oxide finish, this gage measures a nominal diameter of 0.026 inches with a tolerance of 0.0002 inches, meeting the tight dimensional control requirements expected in precision metrology. At 2.0 inches in overall length, it is sized for handheld use during inspection routines. A Certificate of Accuracy with NIST traceability is included, supporting quality management documentation requirements. Licensed metrologists, machinists, and quality control technicians rely on this type of gage for repeatable, standards-compliant bore verification.

This plug gage is suited for go inspection tasks in manufacturing and metrology environments where sub-thousandth tolerances must be verified. It is appropriate for use alongside set micrometers, verniers, and other precision measuring devices. Applications include incoming inspection, in-process quality control, and final part acceptance on machined components requiring close bore tolerances. It conforms to ASME B89.1 standards, making it appropriate for regulated production and calibration lab environments.

Installation Notes

Plug gages of this class are handled and used by trained quality control technicians or metrologists in inspection environments. The gage should be stored in a clean, temperature-stable environment to preserve dimensional accuracy. Avoid dropping or applying lateral force during inspection, as impact or misalignment can alter gage geometry. Clean mating bores and the gage surface before use to prevent measurement errors caused by debris or burrs.
