Vermont Gage 141102550 Class X Plus Pin Gage 0.0255 in

Product Description

The VERMONT GAGE 141102550 is a Class X Plus precision pin gage manufactured from tool steel, sized at 0.0255 inches in diameter and 2 inches in length. It holds a tolerance of +0.00004 inches, placing it in the tightest commercially available gage class. A surface finish of 4 microinches contributes to measurement accuracy and consistent contact across repeated uses. Each unit ships with a Certificate of Accuracy traceable to NIST standards. This gage is used by quality control technicians, machinists, and metrology professionals who require a reliable reference for direct part gaging or instrument calibration.

This pin gage is suited for shop-floor and lab environments where precise hole diameter verification or calibration of measuring equipment is required. Its 0.0255-inch diameter targets small-bore applications common in precision machining, tooling, and inspection work. The compact 2-inch length makes it practical for use in fixtures, comparator stands, or hand-held inspection. The included NIST-traceable certificate supports ISO and AS9100 quality documentation requirements.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision gaging
• Tool steel construction for durability and wear resistance
• 4-microinch surface finish for consistent, repeatable contact
• NIST-traceable Certificate of Accuracy included with each unit
• 0.0255-inch diameter targets small-bore inspection applications
• 2-inch length compatible with standard gage fixtures and comparator setups

Compatibility

Designed for use as a go or no-go reference gage in precision hole inspection and for calibration of measuring equipment requiring a 0.0255-inch diameter reference standard.

Installation Notes

Pin gages are handled by metrology technicians and quality control personnel. Always store pin gages in their protective case when not in use to prevent surface damage. Clean the gage and the workpiece bore with a lint-free cloth before use to remove debris that could affect measurement accuracy. Do not force the pin into a bore; excessive insertion force can damage both the gage and the part surface.
