Vermont Gage 111108900 Class Zz Plus Plug Gage 0.089 in

Product Description

The VERMONT GAGE 111108900 is a Class ZZ Plus plug gage designed to verify bore and hole diameters to tight tolerances in production and inspection environments. With a nominal measurement diameter of 0.089 inches and a tolerance of 0.0002 inches, this gage delivers the precision required for Go inspection work. The 10 microfinish surface finish reduces wear and maintains dimensional integrity over repeated use cycles. Manufactured from tool steel, it provides the hardness and stability expected in gaging applications. A Certificate of Accuracy with NIST Traceability is included, supporting compliance documentation. Machinists, quality technicians, and metrology professionals use this gage in incoming inspection, in-process checks, and final verification.

This plug gage is suited for Go inspection of small-diameter bores and holes in precision machined components. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a known reference standard. The 0.089-inch diameter range addresses fine-tolerance work common in aerospace, automotive, and general manufacturing inspection. The overall length of 2.0 inches provides comfortable handling during bench and floor inspection tasks. Meets ASME B89.1 dimensional standards.

Key Features

Compatibility

Designed for Go inspection of bores and holes at 0.089 inches nominal diameter and for use as a reference standard with micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection environments. Store the gage in its protective case when not in use and keep it free of contaminants that can affect measurement accuracy. Apply a light coat of instrument-grade oil during storage to prevent corrosion on the tool steel surface. Handle with clean, dry hands or lint-free gloves to avoid introducing dimensional error from thermal expansion or surface contamination.
