Vermont Gage 111117300 Class Zz Plus Plug Gage 0.173 in

Product Description

The VERMONT GAGE 111117300 is a Class ZZ Plus plug gage machined from tool steel for precision dimensional inspection. It measures a nominal diameter of 0.173 inches with a tolerance of 0.0002 inches, meeting the tight requirements of ASME B89.1. The 10 microfinish surface provides consistent, repeatable contact during inspection. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in manufacturing and metrology environments. Machinists, quality technicians, and tool-room professionals use this gage to verify bore and hole dimensions with confidence.

This plug gage is designed for go inspection of drilled, reamed, or bored holes at the 0.173-inch nominal diameter. It is also used to calibrate and verify setting accuracy on set micrometers, verniers, and other precision measuring devices. The 2.0-inch overall length provides a comfortable, stable grip during hand-held inspection. Typical applications include production floor inspection, incoming quality control, and toolroom calibration work in both job-shop and high-volume manufacturing settings.

Key Features

• Class ZZ Plus tolerance rating per ASME B89.1 for reliable go inspection
• 0.0002-inch tolerance for tight dimensional verification
• 10 microfinish surface for consistent gage-to-bore contact
• Tool steel construction for durability and wear resistance
• Includes Certificate of Accuracy with NIST Traceability for documentation compliance
• 2.0-inch overall length for easy single-hand use

Compatibility

Designed for go inspection of holes and bores at 0.173 inches nominal diameter, and for use as a setting standard with set micrometers, verniers, and other precision measuring devices.

Installation Notes

This gage is handled by quality technicians and tool-room machinists and requires no installation in the traditional sense. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Handle with clean, dry hands or cotton inspection gloves to avoid contamination of the precision surface. Periodic cleaning with a lint-free cloth and light application of instrument oil will maintain surface finish and extend service life.
