Vermont Gage 141145200 Class X Plus Pin Gage 0.452 in

Product Description

The VERMONT GAGE 141145200 is a Class X Plus pin gage used to verify hole dimensions and calibrate measuring equipment to tight tolerances. Manufactured from tool steel with a 4 micro finish, this gage holds a diameter of 0.452 inches with a tolerance of +0.00004 inches, placing it in the highest common accuracy class for pin gages. At 2 inches in length, it fits standard gage holders and handles. Each unit ships with a Certificate of Accuracy backed by NIST traceability, satisfying ISO and quality-system audit requirements without additional documentation steps. Quality technicians, metrologists, and tool-room machinists are the primary users.

This pin gage is suited for production inspection, incoming inspection, and calibration lab use across manufacturing, machining, and assembly environments. It is used to directly gage bored, drilled, or reamed holes and to verify the accuracy of CMM fixtures, air gages, and other dimensional measuring instruments. Applications span aerospace, automotive, medical device, and general precision machining shops where Class X Plus tolerances are required by process control plans or customer quality requirements.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision dimensional verification
• Tool steel construction provides wear resistance and dimensional stability
• 4 micro surface finish reduces measurement variability at the contact surface
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• 0.452 inch diameter at 2 inches length fits standard pin gage handles and holders

Compatibility

Designed as a direct-use pin gage compatible with standard pin gage handles and sets used in tool rooms and inspection departments requiring Class X Plus accuracy at 0.452 inches nominal diameter.

Installation Notes

Pin gages are handled and stored by metrology or quality personnel following established gage handling procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Always allow the gage and workpiece to reach the same ambient temperature before measuring to avoid thermal expansion errors. Do not force the gage into a hole; light hand pressure is sufficient for proper dimensional verification.
