Vermont Gage 112101460 Class Zz Plus Plug Gage 1.46mm

Product Description

The VERMONT GAGE 112101460 is a Class ZZ Plus plug gage machined from tool steel and designed for precise hole diameter verification in production and quality-control environments. The gage measures 1.46 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-accuracy inspection work where tight dimensional control is required. The 10 microfinish surface provides a consistent, repeatable contact surface. Overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements for ISO and other quality management systems. Licensed metrologists, quality technicians, and precision machinists are the primary users.

This plug gage is used in go inspection applications to verify that a hole or bore meets its minimum allowable diameter. It is also suited for setting and calibrating micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical deployment is in machine shops, manufacturing cells, and metrology labs handling precision small-bore work. The 1.46 mm diameter targets fine-pitch and small-bore applications common in instrument, medical device, and electronics manufacturing.

Key Features

• Class ZZ Plus tolerance classification: 0.00508 mm tolerance for high-accuracy inspection
• Tool steel construction for durability and dimensional stability in production environments
• 10 microfinish surface for consistent, repeatable gage contact
• NIST-traceable Certificate of Accuracy included with each unit
• Conforms to ASME B89.1 standards for plain plug gages
• Compact 2.0-inch overall length suitable for benchtop and handheld use

Compatibility

Designed for use as a go inspection gage for holes and bores at 1.46 mm nominal diameter, and as a setting reference for micrometers, verniers, and other measuring devices requiring a traceable standard at this diameter.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists — no power tools or trade licensing is required for normal use. Clean the gage and the workpiece bore before each measurement to prevent debris from affecting readings or damaging the gage surface. Never force a plug gage into a bore; damage to the gage or workpiece may result. Store the gage in its protective case when not in use to preserve the microfinish and dimensional integrity.
