Vermont Gage 111320350 Class Zz Plus Plug Gage 0.2035 in

Product Description

The VERMONT GAGE 111320350 is a Class ZZ Plus plug gage machined from tool steel and ground to a 0.2035-inch diameter with a tolerance of 0.0002 inches. It measures 2.0 inches in overall length and features a 10 microfinish surface, which is standard for precision go-inspection gaging. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming dimensional compliance to ASME B89.1. Machinists, quality technicians, and metrology lab personnel use this gage to verify hole diameters during production and inspection workflows.

This plug gage is suited for go-inspection applications in manufacturing and quality control environments. It is designed to check that bored, drilled, or reamed holes at 0.2035 inches fall within acceptable dimensional limits. It is also compatible with calibration setups for setting micrometers, verniers, and other measuring devices. The Class ZZ Plus designation indicates tighter tolerance control compared to standard Class ZZ gages, making it appropriate for closer-tolerance work in both job shop and production inspection settings.

Key Features

• 0.2035-inch nominal diameter with 0.0002-inch tolerance per ASME B89.1
• 10 microfinish surface for consistent, low-wear contact
• Tool steel construction for durability under repeated use
• Certificate of Accuracy included with NIST traceability
• Compatible with go-inspection, micrometer setting, and vernier calibration tasks
• 2.0-inch overall length for standard hand-held use

Compatibility

Designed for go-inspection use with bored, drilled, or reamed holes at 0.2035 inches, and for setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no installation tools are required. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Never force the gage into an undersized hole, as this can damage both the gage surface and the workpiece. Clean the gage and the part bore with a lint-free cloth before inspection to ensure accurate readings.
