Vermont Gage 141130900 Class X Plus Pin Gage 0.309 in

Product Description

The VERMONT GAGE 141130900 is a Class X Plus pin gage manufactured from tool steel, designed for precision dimensional inspection in industrial and metrology environments. With a nominal diameter of 0.309 inches and a tolerance of +0.00004 inches, this gage meets the tight tolerances required for Class X Plus classification. It measures 2 inches in length and carries a 4 micro surface finish. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for use in calibration programs and quality systems that require documented traceability.

This pin gage is used to calibrate measuring equipment or to directly gage machined holes, bores, and other precision features on manufactured parts. It is appropriate for use in machine shops, inspection departments, tool rooms, and calibration labs. Typical applications include go/no-go gauging of drilled or reamed holes, verification of measuring instrument accuracy, and dimensional audits on production parts. The 2-inch length allows for access into most standard bore depths encountered in general manufacturing work.

Key Features

• Class X Plus tolerance: +0.00004 inches for high-precision inspection work
• Tool steel construction for hardness, wear resistance, and dimensional stability
• 4 micro surface finish for smooth, consistent contact during measurement
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Suitable for direct part gauging or calibration of measuring equipment

Compatibility

Designed as an OEM-style precision inspection tool for use in any application requiring a 0.309-inch diameter Class X Plus pin gage, including direct hole gauging and calibration of measuring equipment.

Installation Notes

Pin gages should be handled by metrology technicians or quality inspection personnel following standard gage handling procedures. Keep gages clean and lightly oiled when not in use to prevent corrosion. Do not force a pin gage into a feature under inspection, as this may damage the gage or the part. Store in the original protective case or a padded gage roll to maintain surface finish and dimensional integrity.
