Vermont Gage 141107800 Class X Plus Pin Gage 0.078 in

Product Description

The VERMONT GAGE 141107800 is a Class X Plus precision pin gage used to verify hole diameters and bore dimensions with high accuracy. Machined from tool steel with a 4 micro-inch finish, it measures 0.078 inches in diameter and 2 inches in length. The tolerance is held to +0.00004 inches, placing it in the tightest commercially available gage class. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented quality-control processes. Metrology technicians, toolroom machinists, and quality inspectors are the primary users of this type of gage.

This pin gage is used in calibration labs, machine shops, and manufacturing environments where precise bore and hole verification is required. It is appropriate for both go/no-go inspection workflows and direct dimensional checks on machined parts. At 0.078 inches in diameter, it targets small-bore applications common in precision machined components, medical device manufacturing, and instrument assembly.

Key Features

• Class X Plus tolerance of +0.00004 inches for highest-accuracy inspection
• Tool steel construction for wear resistance and dimensional stability
• 4 micro-inch surface finish for accurate, repeatable contact measurement
• NIST-traceable Certificate of Accuracy included for quality documentation
• Compact 2-inch length suitable for handheld use and tight-access applications

Compatibility

Designed for use as a precision measurement reference in calibration of measuring equipment or for direct gaging of machined parts requiring a 0.078-inch nominal diameter check.

Installation Notes

Pin gages are handled by metrology and quality-control personnel, not typically installed in the traditional sense. Store in a protective case away from moisture and contaminants to preserve the surface finish and dimensional integrity. Clean contact surfaces before each use and allow the gage to thermally stabilize to the measurement environment before taking readings. Do not force a pin gage into an undersized bore, as this will damage both the gage and the workpiece.
