Vermont Gage 141143850 Class X Plus Pin Gage 0.4385 in

Product Description

The VERMONT GAGE 141143850 is a Class X Plus precision pin gage designed for direct part gaging and calibration of measuring equipment. It measures 0.4385 inches in diameter with a tightly controlled tolerance of plus 0.00004 inches, placing it firmly in the Class X Plus accuracy range. The gage is 2 inches long and machined from tool steel with a 4 micro finish. A Certificate of Accuracy with NIST traceability is included, supporting documented quality systems and inspection workflows. Dimensional inspection technicians, quality engineers, and calibration lab personnel are the primary users.

This pin gage is suited for use in inspection rooms, machine shops, and calibration labs where precise bore, hole, or slot verification is required. The 0.4385-inch diameter targets applications where tight go/no-go or attribute inspection is performed on machined parts, fixtures, or tooling. The included NIST-traceable certificate makes it appropriate for use in ISO 9001, AS9100, and similar quality management environments where documentation of gage traceability is mandatory.

Key Features

• Class X Plus tolerance of plus 0.00004 inches for high-precision inspection work
• Tool steel construction provides durability and dimensional stability under repeated use
• 4 micro surface finish supports accurate contact measurement
• Includes Certificate of Accuracy with NIST traceability for documented quality systems
• Compact 2-inch length suits bench inspection and inline gaging applications

Compatibility

Designed as an OEM-style replacement or direct-use precision gage for applications requiring a 0.4385-inch diameter Class X Plus pin gage in dimensional inspection and calibration settings.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent surface contamination that could affect measurement accuracy. Store the gage in its case when not in use and apply a light coat of instrument-grade oil if long-term storage is anticipated. Allow the gage and workpiece to reach the same ambient temperature before use to eliminate thermal expansion errors. Calibration intervals should follow your facility quality plan and applicable metrology standards.
