Vermont Gage 111170700 Class Zz Plus Plug Gage 0.707in

Product Description

The VERMONT GAGE 111170700 is a Class ZZ Plus plug gage used to verify bore and hole diameters to tight dimensional tolerances in precision inspection work. Built from tool steel, it measures at a nominal diameter of 0.707 inches with a tolerance of 0.0002 inches and a 10 microinch surface finish. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for calibration-controlled environments. Metrology technicians, quality inspectors, and toolroom machinists use this gage to confirm that machined features meet specification before parts advance through production.

This plug gage is designed for go-type inspection of holes, bores, and internal diameters at the 0.707-inch nominal size. It is also used to set and verify go/no-go decisions on micrometers, verniers, and other dimensional measuring devices. Typical applications include incoming inspection, in-process quality control, and final part acceptance in manufacturing and machine shop environments. The overall handle and gage member length is 2.0 inches, making it easy to manipulate in standard bench inspection setups.

Key Features

• Class ZZ Plus tolerance grade: 0.0002 inches, suitable for precision go inspection
• 10 microinch surface finish for consistent, repeatable gage contact
• Tool steel construction for durability and wear resistance in production use
• Meets ASME B89.1 dimensional standard
• Includes Certificate of Accuracy with NIST traceability for calibration records
• Compact 2.0-inch overall length for bench or hand-held inspection use

Compatibility

Designed for go inspection of 0.707-inch nominal diameter bores and holes, and for use as a setting standard with micrometers, verniers, and other dimensional measuring devices.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, inspect the gage member for nicks or wear and confirm calibration status against the certificate. Store in a protective case away from abrasive materials and temperature extremes to maintain dimensional integrity. Gage replacement or recalibration should be performed by a qualified metrology technician in accordance with your facility quality management system.
