Vermont Gage 112403410 Class Zz Minus Plug Pin Gage 3.41mm

Product Description

The VERMONT GAGE 112403410 is a Class ZZ minus plug pin gage machined from steel and used to perform NoGo dimensional inspection on bored holes and machined features. The gage measures 3.41 mm in diameter with a tolerance of 0.00508 mm, making it suitable for precision go/no-go gauging workflows where tight dimensional control is required. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, satisfying documentation requirements for calibrated inspection tooling in quality-controlled environments. Machinists, toolmakers, and dimensional inspection technicians are the primary users of this gage.

This plug pin gage is intended for NoGo inspection applications and is also suited for setting micrometers, verniers, and other measuring devices that require a known reference diameter. It fits into standard gage-pin workflows in machine shops, fabrication facilities, and inspection labs where NIST-traceable documentation is required. The 10 microfinish coating on the gage surface supports accurate seating in bores and minimizes wear on the contact surface during repeated use.

Key Features

• 3.41 mm diameter with 0.00508 mm tolerance for precision dimensional checks
• NIST-traceable Certificate of Accuracy included with each unit
• 10 microfinish surface coating for consistent contact and reduced wear
• Steel construction for durability in production and inspection environments
• Overall length of 2 inches for standard gage-pin handling

Compatibility

Designed for use in NoGo plug gage inspection applications and for setting micrometers, verniers, and other measuring devices requiring a 3.41 mm reference diameter.

Installation Notes

This gage is handled by inspection and metrology personnel and does not require mechanical installation. Store the gage in a protective case when not in use to prevent surface damage or contamination that could affect measurement accuracy. Handle only with clean, dry hands or lint-free gloves to avoid corrosion and dimensional errors from oils or particulates. Verify calibration documentation is current before use in a quality-controlled inspection process.
