Vermont Gage 111234100 Class Zz Minus Plug Pin Gage 0.3410 in

Product Description

The VERMONT GAGE 111234100 is a Class ZZ Minus tolerance plug pin gage ground to a diameter of 0.3410 inches with a tolerance of 0.0002 inches. This gage is used to perform NoGo inspection checks on machined bores, holes, and features to verify that a dimension does not exceed its maximum allowable limit. The steel construction provides durability under repeated shop-floor use. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting documentation requirements for calibrated inspection tooling in quality-controlled environments.

This plug pin gage is suited for use in machine shops, manufacturing facilities, and inspection departments where dimensional verification of drilled or reamed holes is required. It is also applied when setting micrometers, verniers, and other measuring devices to a known reference diameter. The 0.3410 inch diameter and 2 inch overall length make it practical for checking shallow to moderate-depth bores in production or incoming inspection workflows.

Key Features

• Class ZZ Minus tolerance ground to 0.3410 inches diameter with 0.0002 inch tolerance
• Steel construction for wear resistance and dimensional stability
• 10 microfinish surface coating for consistent, accurate contact
• Includes Certificate of Accuracy with NIST Traceability for quality documentation
• 2 inch overall length suitable for standard bore inspection tasks
• Functions as a NoGo gage and as a reference standard for setting measuring instruments

Compatibility

Designed for NoGo inspection of machined holes and bores, and for use as a reference standard when setting micrometers, verniers, and other precision measuring devices requiring a 0.3410 inch diameter reference.

Installation Notes

Plug pin gages are handled and used by quality technicians, machinists, and metrology personnel. Store the gage in its protective case when not in use to prevent damage to the ground surface. Clean the gage and the bore being checked before use to avoid false readings caused by debris or oil film. Never force a plug gage into a hole; if resistance is felt, the hole is undersize and should be remeasured before proceeding.
