Vermont Gage 111160200 Class Zz Plus Plug Gage 0.602 in

Product Description

The VERMONT GAGE 111160200 is a Class ZZ Plus cylindrical plug gage manufactured from tool steel for dimensional go inspection work. It measures a nominal diameter of 0.602 inches with a tolerance of 0.0002 inches and a 10 microinch surface finish. At 2.0 inches overall length, this gage is sized for easy single-hand use on the shop floor or inspection bench. A Certificate of Accuracy with NIST Traceability ships with each unit, satisfying documentation requirements for quality management systems. Machinists, quality technicians, and metrology professionals use this gage to verify whether a drilled, reamed, or bored hole falls within specification before the part advances to the next operation.

This plug gage is suited for go inspection of holes at the 0.602-inch nominal diameter. It is also appropriate for setting and verifying the calibration of micrometers, verniers, and other handheld measuring devices where a certified reference standard is required. The tool steel construction handles the wear demands of moderate production inspection cycles. Compliance with ASME B89.1 makes this gage acceptable in environments where adherence to recognized dimensional metrology standards is required by contract or customer specification.

Key Features

• Class ZZ Plus tolerance grade: 0.0002 inches, suitable for general-purpose go inspection
• 10 microinch surface finish for consistent, repeatable contact with the measured bore
• Tool steel construction resists wear during routine production inspection use
• Meets ASME B89.1 dimensional metrology standard
• Includes Certificate of Accuracy with NIST Traceability for QMS documentation
• 2.0 inches overall length provides a compact, balanced feel for bench or floor use

Compatibility

Designed for go inspection of holes with a nominal diameter of 0.602 inches. Also used to set micrometers, verniers, and other measuring devices requiring a certified dimensional reference at this diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists following established metrology procedures. Before use, clean the gage and the bore being inspected to remove chips, coolant, and debris that could affect the measurement or damage the gage surface. Apply light gaging oil or handle the gage with clean cotton or nitrile gloves to prevent corrosion from skin contact. Store the gage in its case when not in use to protect the lapped surface finish and maintain calibration integrity.
