Vermont Gage 141137700 Class X Plus Pin Gage 0.377 in

Product Description

The VERMONT GAGE 141137700 is a Class X Plus precision pin gage manufactured from tool steel for dimensional inspection and measurement verification work. It measures 0.377 inches in diameter and 2 inches in length, with a tolerance of +0.00004 inches, placing it in the tightest class of pin gage accuracy available for go/no-go and direct part gaging applications. A surface finish of 4 microinch ensures consistent, repeatable contact with bores, holes, and features under inspection. Every unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO-compliant and calibration-controlled environments. Dimensional inspection technicians, machinists, and quality control personnel are the primary users of this gage.

This pin gage is suited for use in metrology labs, machine shops, and production quality control settings where hole diameter verification, bore gaging, or calibration of measuring equipment is required. It is appropriate for both incoming inspection and in-process checks on machined parts. The 2-inch length provides adequate handling clearance for most bench-top inspection setups. Applications include direct gaging of drilled, reamed, or bored holes as well as functional verification of fixtures, jigs, and other precision tooling components.

Key Features

• Class X Plus tolerance of +0.00004 inches for the highest level of pin gage accuracy
• Tool steel construction for hardness, wear resistance, and dimensional stability
• 4 microinch surface finish for precise, repeatable contact measurement
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• 0.377 inch diameter, 2 inch length for standard bench-top inspection use
• Individual unit packaging with a minimum order quantity of 1

Compatibility

Designed for use as a precision measurement reference in any inspection or calibration process requiring a 0.377-inch Class X Plus pin gage, including direct hole gaging and calibration of measuring equipment.

Installation Notes

Pin gages are handled and used by metrology technicians and quality control personnel, not installed in mechanical systems. Store the gage in its protective sleeve or case when not in use to prevent surface damage and corrosion. Clean the gage and the feature being measured before use to avoid debris-induced measurement errors. Do not force the gage into an undersized hole, as this can damage the gage surface and compromise its tolerance class.
