Vermont Gage 141132100 Class X Plus Pin Gage 0.321 in

Product Description

The VERMONT GAGE 141132100 is a Class X Plus precision pin gage designed for direct part gaging and calibration of measuring equipment. It measures 0.321 inches in diameter and 2 inches in length, machined from tool steel with a 4 micro-inch surface finish. The Class X Plus tolerance is held to +0.00004 inches, placing it among the tightest commercially available gage grades. Each unit ships with a Certificate of Accuracy that carries NIST traceability, satisfying documentation requirements for ISO and quality-system audits. Metrologists, tool room technicians, and quality control professionals use this gage for go/no-go inspection, hole diameter verification, and instrument calibration routines.

This pin gage is suited for production floor inspection and metrology lab use across manufacturing, machining, and fabrication environments. Its 2-inch working length provides adequate grip and handling clearance for insertion into bores, slots, and precision fixtures. The tool steel construction and fine surface finish make it appropriate for both routine production checks and reference-grade calibration tasks where tight dimensional tolerance documentation is required.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision dimensional verification
• Tool steel construction for durability and dimensional stability
• 4 micro-inch surface finish for consistent, accurate contact measurement
• Includes Certificate of Accuracy with NIST traceability for audit and quality-system compliance
• 0.321-inch diameter, 2-inch length for straightforward bore and hole inspection

Compatibility

Designed as an OEM-style precision gage suitable for use with standard pin gage handles and sets compatible with 0.321-inch diameter Class X Plus members.

Installation Notes

Pin gages should be handled with clean, lint-free gloves or a cloth to prevent contamination from skin oils that can affect measurement accuracy. Store in the provided case or a controlled-environment gage block cabinet away from humidity and temperature extremes. Clean the gage and the measured bore or hole prior to use following standard metrology practice. Do not force the pin into an undersized feature, as this can damage the gage surface and invalidate the NIST-traceable calibration certificate.
