Vermont Gage 141135500 Class X Plus Pin Gage 0.355 in

Product Description

The VERMONT GAGE 141135500 is a Class X Plus precision pin gage manufactured from tool steel. It measures 0.355 inches in diameter and 2 inches in length, with a tight tolerance of +0.00004 inches. The surface finish is held to 4 microinch, which is standard for Class X Plus designation. This gage is used by machinists, quality technicians, and metrologists to verify hole sizes and calibrate measuring equipment to a traceable standard. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for use in ISO-compliant quality systems. At 0.1 pounds, it is lightweight and easy to handle in production or lab environments.

This pin gage is intended for direct gaging of machined parts or for calibrating and verifying measuring instruments. It is commonly used in machine shops, manufacturing facilities, and metrology labs where hole tolerance verification is required. The Class X Plus classification indicates it meets one of the tightest commercially available tolerance grades for go/no-go and attribute gaging applications. It is appropriate for both incoming inspection and in-process quality control work across general manufacturing environments.

Key Features

• Class X Plus tolerance grade: +0.00004 inches for high-precision gaging
• Tool steel construction for durability and dimensional stability
• 4 microinch surface finish meets Class X Plus requirements
• Includes Certificate of Accuracy with NIST traceability
• Suitable for direct part gaging and calibration of measuring equipment
• Lightweight at 0.1 pounds for easy single-hand use

Compatibility

Designed for use as a precision attribute gage in standard pin gage sets and holders compatible with 0.355-inch diameter pin gages. Suitable for use in any metrology or quality control application requiring NIST-traceable Class X Plus gaging at this diameter.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and contamination of the precision surface. Store in the provided case or a protected gage block cabinet away from humidity and temperature extremes. Clean gaging surfaces with a lint-free cloth and light oil before and after use to maintain accuracy and prevent rust on the tool steel. Do not force the pin gage into a hole; if resistance is met, verify the hole size with another method before proceeding.
