Vermont Gage 141125030 Class X Plus Pin Gage 0.2503 in

Product Description

The VERMONT GAGE 141125030 is a Class X Plus precision pin gage used to verify bore diameters, hole sizes, and slot widths in machined components. It measures 0.2503 inches in diameter and 2 inches in length, holding a tolerance of +0.00004 inches — the tightest classification in the go/no-go gage system. Manufactured from tool steel with a 4 microinch surface finish, it delivers the dimensional consistency required for quality control and calibration work. Each unit ships with a Certificate of Accuracy traceable to NIST standards, satisfying traceability requirements for ISO and AS9100-compliant inspection programs.

This pin gage is suited for use in machine shops, toolrooms, and inspection departments where tight-tolerance hole verification is required. Typical applications include checking drilled, reamed, or bored holes in production parts, as well as calibrating measuring equipment. The Class X Plus classification makes it appropriate for the most demanding dimensional inspection tasks where standard Class X or ZZ gages do not provide sufficient tolerance control.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision measurement applications
• Tool steel construction with 4 microinch surface finish for durability and dimensional stability
• 0.2503 inch diameter, 2 inch length for direct part gaging or equipment calibration
• Includes Certificate of Accuracy with NIST traceability to support quality system documentation
• Suitable for calibration of measuring equipment or direct gaging of machined parts

Compatibility

Designed as an OEM-style precision measurement tool for use with standard pin gage handles and compatible with inspection setups requiring NIST-traceable Class X Plus go/no-go pin gages at 0.2503 inch nominal diameter.

Installation Notes

Pin gages are handled and used by quality technicians, toolroom machinists, and metrologists. Store in a protective case away from moisture and temperature extremes to maintain dimensional integrity. Clean the gage and the hole to be measured before use to prevent debris from affecting readings. Do not force the pin into a bore; if resistance is encountered, inspect the part and gage for contamination or burrs.
