Vermont Gage 111135800 Class Zz Plus Plug Gage 0.358 in

Product Description

The VERMONT GAGE 111135800 is a Class ZZ Plus plug gage machined from tool steel for precision dimensional inspection work. It measures a nominal diameter of 0.358 inches with a tolerance of 0.0002 inches and a surface finish of 10 microinch Ra. These plug gages are used by machinists, quality technicians, and metrology professionals to verify bore and hole dimensions against fixed limits. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming conformance to ASME B89.1 dimensional standards. The tool steel construction provides the hardness and wear resistance required for repeated gauging cycles in production and inspection environments.

This plug gage is suited for go inspection applications in manufacturing quality control, toolroom verification, and calibration bench setups. It is compatible with use alongside set micrometers, vernier calipers, and other precision measuring devices as a reference standard. Typical users include QC inspectors and machinists performing first-article inspections, in-process checks, or final acceptance gauging on machined bores and drilled holes requiring close diameter tolerances.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inch dimensional tolerance for precise go-limit inspection
• 10 microinch Ra surface finish for repeatable, low-wear gauge contact
• Tool steel construction for hardness and resistance to wear in production use
• Includes Certificate of Accuracy with NIST traceability per ASME B89.1
• Overall length of 2.0 inches for comfortable handling and compatibility with standard gage handles

Compatibility

Designed for use in go inspection applications alongside set micrometers, verniers, and other precision measuring devices. Suitable as an OEM-style plug gage for bore and hole inspection in standard toolroom and quality control setups.

Installation Notes

Plug gages should be handled by metrology or quality control personnel following standard gauging practices. Clean the gage and the bore being inspected before use to prevent debris from affecting readings or causing surface damage. Store the gage in its case away from other metal tools to protect the finish and maintain calibration. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece.
