Vermont Gage 141137400 Class X Plus Pin Gage 0.374 in

Product Description

The VERMONT GAGE 141137400 is a Class X Plus pin gage designed for high-precision dimensional inspection. With a diameter of 0.374 inches and a length of 2 inches, this gage is manufactured from tool steel and features a 4 micro surface finish. Class X Plus represents one of the tightest commercially available tolerance grades, with a tolerance of +0.00004 inches on the nominal diameter. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for use in calibrated measurement systems. Machinists, quality technicians, and calibration lab personnel use this tool as a primary reference standard or for direct part inspection.

This pin gage is used in production and quality control environments to verify bore diameters, slot widths, and feature locations. It is well suited for calibrating measuring equipment or for direct gaging of machined parts where tight tolerances must be confirmed. Typical applications include incoming inspection, first-article inspection, and calibration laboratory use across manufacturing, aerospace, automotive, and general machining operations.

Compatibility

Designed as an OEM-style replacement or addition to pin gage sets used in dimensional inspection and calibration applications requiring a 0.374 inch diameter Class X Plus gage member.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in a protective case away from magnetic fields and temperature extremes to maintain dimensional stability. When used for calibration, allow the gage to thermally stabilize to the measurement environment before use. Periodic recalibration per your facility quality management system is recommended to maintain measurement integrity.
