Vermont Gage 141109100 Class X Plus Pin Gage 0.091 in

Product Description

The VERMONT GAGE 141109100 is a Class X Plus pin gage machined from tool steel for high-precision diameter measurement and part verification. At 0.091 inches in diameter and 2 inches in length, this gage holds a tolerance of +0.00004 inches, placing it in the tightest commercially available accuracy class. A Certificate of Accuracy with NIST traceability ships with each unit, supporting documented quality systems and calibration programs. The 4 micro-inch surface finish on the gage pin contributes to consistent, repeatable contact with the workpiece or instrument bore. Calibration technicians, quality inspectors, and precision machinists use this type of gage in both shop-floor and metrology lab environments.

This pin gage is suited for direct gaging of precision holes and bores or for calibrating and verifying measuring equipment. Typical applications include go/no-go functional checks on machined parts, calibration of dial bore gages, and verification of air gage masters. The Class X Plus designation makes it appropriate for applications where standard Class X tolerances are insufficient and traceable accuracy documentation is required by the quality system.

Key Features

• Class X Plus tolerance of +0.00004 inches for ultra-precision diameter verification
• Tool steel construction provides hardness and wear resistance for repeated use
• 4 micro-inch surface finish supports accurate, low-friction contact measurement
• Includes Certificate of Accuracy with NIST traceability for documented calibration programs
• Compact 2-inch length fits standard pin gage handles and collet-style holders

Compatibility

Designed for use with standard pin gage handles and compatible with calibration programs requiring NIST-traceable Class X Plus gaging in the 0.091-inch diameter range.

Installation Notes

Pin gages should be handled with clean cotton or nitrile gloves to prevent corrosion from skin oils. Store in the provided case or a protected gage block cabinet when not in use. Clean mating bores and instrument fixtures before insertion to avoid false readings or surface damage. Calibration intervals should follow the requirements of your quality management system and applicable metrology standards.
