Vermont Gage 112201760 Class Zz Plug Pin Gage 1.76mm

Product Description

The VERMONT GAGE 112201760 is a Class ZZ Minus plug pin gage machined from steel for precision dimensional inspection. At 1.76 mm diameter with a tolerance of 0.00508 mm, it provides reliable NoGo gauging for verifying that a hole or feature does not exceed its maximum allowable size. The 10 microfinish surface coating reduces wear and ensures consistent contact during measurement. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting documentation requirements for calibrated inspection environments. Metrology technicians, quality control inspectors, and precision machinists use this gage in production and incoming inspection workflows.

This plug pin gage is suited for NoGo inspection of small-diameter bores in precision machined components. It is also used to set and verify micrometers, verniers, and other measuring devices where a known reference diameter is required. The 2-inch overall length provides adequate handling clearance for bench-top inspection work. Applications span aerospace, medical device manufacturing, general machining, and any quality program requiring documented, traceable dimensional verification at the 1.76 mm nominal diameter.

Key Features

• Class ZZ Minus tolerance of 0.00508 mm for NoGo gauging applications
• Steel construction with 10 microfinish surface coating for durability and accuracy
• NIST-traceable Certificate of Accuracy included with each unit
• Compatible with micrometer, vernier, and bore-gauging setups as a reference standard
• Compact 2-inch overall length suited for bench-top and in-process inspection

Compatibility

Designed for NoGo inspection use and for setting micrometers, verniers, and other measuring devices requiring a 1.76 mm reference diameter. Consult your gauging system specifications to confirm nominal diameter and tolerance class requirements before installation.

Installation Notes

Plug pin gages should be handled with clean, lint-free gloves or gauge-handling tools to prevent contamination and corrosion from skin oils. Store in the provided case or a protected gauge tray when not in use. Clean the gage and the feature being measured before use to ensure accurate contact. Periodic recalibration against a certified reference standard is recommended to maintain measurement integrity over time.
