Vermont Gage 141218150 Class X Minus Pin Gage 0.1815 in

Product Description

The VERMONT GAGE 141218150 is a Class X Minus pin gage designed for high-precision measurement work in metrology, quality control, and machining environments. It measures 0.1815 inches in diameter and 2 inches in length, with a tolerance of -0.00004 inches, placing it firmly in the Class X accuracy tier. The gage is manufactured from tool steel and features a 4 microinch surface finish. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for calibration programs that require documented measurement standards. Precision measurement technicians, machinists, and quality engineers are the primary users of this tool.

This pin gage is used to calibrate measuring equipment or to directly gage part features such as holes, slots, and bores in manufacturing and inspection settings. It is appropriate for both shop-floor and laboratory use wherever tight tolerances must be verified. The NIST-traceable certificate supports ISO and AS9100 quality management systems, tool crib documentation, and gage calibration records. Applications span aerospace, automotive, and general machining environments where sub-thousandth measurement accuracy is required.

Key Features

• Class X Minus tolerance of -0.00004 inches for high-accuracy measurement
• 0.1815 inches diameter with 4 microinch surface finish for consistent gage contact
• Tool steel construction provides hardness and wear resistance for repeated use
• Includes Certificate of Accuracy with NIST traceability for calibration program compliance
• Compact 2 inches length suits bench, crib, and portable inspection kits

Compatibility

Designed as an OEM-style precision gage for use with standard pin gage handle sets and gage block accessories in calibration and direct-part inspection applications.

Installation Notes

Pin gages are handled and deployed by quality technicians, metrologists, and machinists. Always clean the gage and the workpiece bore before use to prevent false readings from debris or oil film. Store in the original case or a protective sleeve to avoid surface damage that would affect tolerance class. Do not force the gage into a bore — a Class X gage used with excessive force can damage both the gage and the part surface.
