Vermont Gage 141147250 Class X Plus Pin Gage 0.4725 in

Product Description

The VERMONT GAGE 141147250 is a Class X Plus precision pin gage used to verify bore diameters and inspect machined holes to tight tolerances. Manufactured from tool steel with a 4 micro-inch surface finish, this gage measures 0.4725 inches in diameter and 2 inches in length. It carries a tolerance of positive 0.00004 inches, placing it in the Class X Plus accuracy class for high-precision inspection work. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for controlled calibration environments and quality assurance workflows. Dimensional inspectors, tool room technicians, and metrology lab personnel are the typical end users.

This pin gage is suited for direct part gaging and calibration of measuring equipment in manufacturing and inspection environments. It is used to check hole size conformance on machined components, verify measuring instrument performance, and establish reference standards in quality control programs. The 2-inch handle length provides adequate grip for manual insertion into bores within the 0.4725-inch nominal diameter range. Applications span precision machining shops, aerospace fabrication, tooling verification, and general metrology.

Key Features

• Class X Plus tolerance of positive 0.00004 inches for high-accuracy inspection
• 0.4725-inch nominal diameter with 2-inch overall length
• Tool steel construction for durability and wear resistance
• 4 micro-inch surface finish for consistent contact measurement
• Includes Certificate of Accuracy with NIST traceability
• Single-piece packaging with minimum order quantity of 1

Compatibility

Designed as an OEM-style Class X Plus go-gage replacement or supplemental inspection tool for applications requiring a 0.4725-inch nominal pin diameter in calibration and direct part-gaging setups.

Installation Notes

Pin gages are handled and stored by dimensional inspection personnel, not field installation trades. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion on the tool steel. Never force the pin into a bore — insertion should be smooth and without lateral pressure to avoid damaging the gage or the part. Store in the original case or a padded gage holder to protect the precision-ground surface finish and maintain NIST-traceable accuracy.
