Vermont Gage 141139500 Class X Plus Pin Gage 0.395 in

Product Description

The VERMONT GAGE 141139500 is a Class X Plus precision pin gage designed for direct part gaging and calibration of measuring equipment. Machined from tool steel with a 4 microinch surface finish, this gage holds a tight tolerance of +0.00004 inches on its 0.395-inch nominal diameter. At 2 inches in length, it delivers the reach needed for most standard bore and hole inspection tasks. Each unit ships with a Certificate of Accuracy that includes NIST traceability, making it suitable for use in calibrated measurement environments. Metrology technicians, quality control inspectors, and tool room machinists rely on this class of gage for repeatable, reliable dimensional verification.

This pin gage is used in shop floor inspection, tool room calibration, and quality lab applications where precise hole and bore sizing is required. It is appropriate for both production gaging of machined parts and periodic calibration checks on measuring instruments. The Class X Plus tolerance class is among the tightest available for go/no-go and attribute gaging work, making it a fit for applications demanding high dimensional accuracy in residential and light commercial manufacturing or maintenance environments.

Key Features

• Class X Plus tolerance: +0.00004 inches for high-precision measurement
• 0.395-inch nominal diameter, 2-inch usable length
• Tool steel construction for hardness and wear resistance
• 4 microinch surface finish for accurate, repeatable contact measurement
• Includes Certificate of Accuracy with NIST traceability
• Suitable for direct part gaging and calibration of measuring equipment

Compatibility

Designed as an OEM-style replacement or supplement pin gage for use with standard pin gage handles and holders accepting 0.395-inch diameter gage pins in Class X Plus tolerance applications.

Installation Notes

Pin gages should be handled with clean, lint-free gloves to prevent contamination from skin oils, which can affect measurement accuracy. Store in a protective case away from humidity and temperature extremes when not in use. Before use, verify the gage and workpiece are at thermal equilibrium, typically at 68 degrees F, per standard metrology practice. Do not force the pin into a bore; light hand pressure is sufficient for accurate gaging.
