Vermont Gage 111153600 Class Zz Plus Plug Gage 0.536 in

Product Description

The VERMONT GAGE 111153600 is a Class ZZ Plus plug gage designed to measure hole diameters with high precision. Built from tool steel, this go-inspection gage holds a diameter of 0.536 inches and a tolerance of 0.0002 inches. The 10 microinch surface finish ensures consistent, reliable contact with the workpiece. It ships with a Certificate of Accuracy that includes NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and tool-room inspectors use this gage to verify whether a drilled or reamed hole falls within acceptable limits on a go-inspection basis. Overall length is 2.0 inches.

This plug gage is suited for dimensional inspection in production and tool-room environments. It is used to verify hole size on machined parts before assembly or final acceptance. Typical applications include go inspection, setting micrometers, and calibrating verniers and other measuring devices. The compact 2.0-inch overall length makes it easy to handle on the bench or at the machine. It is appropriate for both shop-floor inspection and quality-lab use where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus tolerance classification for go-inspection applications
• 0.0002-inch tolerance for precise hole-diameter verification
• 10 microinch surface finish for consistent gage-to-bore contact
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards

Compatibility

Designed for go inspection of holes with a nominal diameter of 0.536 inches. Also used to set micrometers, verniers, and other precision measuring devices requiring a traceable reference standard at this diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no installation in the traditional sense applies. Store the gage in its protective case when not in use to prevent damage to the precision ground surface. Clean the gage and the bore being measured before use to avoid false readings caused by chips or debris. Do not force the gage into the hole; apply only light hand pressure consistent with standard go-gage practice.
