Vermont Gage 141168750 Class X Plus Pin Gage 0.6875 in

Product Description

The VERMONT GAGE 141168750 is a Class X Plus precision pin gage designed for direct part gaging and calibration of measuring equipment. Manufactured from tool steel with a 4 micro finish, this pin gage measures 0.6875 inches in diameter and 2 inches in length. The Class X Plus tolerance of +0.00004 inches places it among the tightest tolerance grades available for go/no-go and attribute gaging work. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibrated measurement environments and quality assurance workflows. Metrology technicians, quality control inspectors, and tool-room machinists are the primary users.

This pin gage is suited for production floor gaging, incoming inspection, and calibration lab applications where tight dimensional verification is required. It is used to verify hole diameters, bore tolerances, and slot widths in machined parts, castings, and fabricated components. The 0.6875-inch diameter targets a common fractional hole size frequently encountered in mechanical assemblies. Its compact 2-inch length makes it easy to handle in confined inspection setups.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision gaging applications
• Tool steel construction provides durability and dimensional stability
• 4 micro surface finish for accurate, repeatable contact measurement
• Includes Certificate of Accuracy with NIST traceability for calibration compliance
• 0.6875-inch diameter targets a standard fractional hole size
• Compact 2-inch length suitable for benchtop and inline inspection use

Compatibility

Designed as an OEM-style replacement and standard-issue precision gage for quality assurance setups requiring a 0.6875-inch Class X Plus pin gage with NIST-traceable certification.

Installation Notes

Pin gages are handled and used by quality control technicians and metrology professionals. Store the gage in its protective case when not in use to prevent surface damage or contamination that could affect accuracy. Clean the gage and the part surface before use to remove oils, debris, or burrs that may cause false readings. Do not force the pin into a hole; excessive insertion force can damage both the gage and the workpiece.
