Vermont Gage 141128400 Class X Plus Pin Gage 0.284 in

Product Description

The VERMONT GAGE 141128400 is a Class X Plus pin gage used to verify hole diameters and bore sizes to a high level of precision. Machined from tool steel with a 4 micro finish, it measures 0.284 inches in diameter and 2 inches in length. The Class X Plus tolerance rating holds to +0.00004 inches, making it suitable for quality control, inspection, and calibration of measuring equipment. Each gage ships with a Certificate of Accuracy traceable to NIST, providing documented traceability for shop and laboratory use. Dimensional inspectors, machinists, and metrology technicians rely on this type of gage where tight tolerance verification is required.

This pin gage is used in manufacturing inspection, tool room environments, and calibration labs where direct part gaging or instrument verification is performed. It is appropriate for residential shop settings and commercial production facilities alike. Typical applications include checking drilled, reamed, or bored holes against a nominal 0.284-inch target diameter. The included NIST-traceable certificate supports ISO and AS9100 quality management documentation requirements.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision inspection work
• Tool steel construction with 4 micro surface finish for consistent gauge contact
• 2-inch length provides a stable grip and adequate insertion depth for typical bore checks
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Single-piece packaging with a minimum order quantity of 1 for easy individual procurement

Compatibility

Designed as an OEM-style precision measurement tool for use in any inspection or calibration application requiring a 0.284-inch diameter Class X Plus pin gage.

Installation Notes

Pin gages are handled and used by dimensional inspectors and machinists and require no mechanical installation. Keep the gage clean and lightly oiled when stored to prevent corrosion on the tool steel surface. Handle with care to avoid dropping, as impact damage can alter the gage diameter and invalidate its tolerance class. Store in the original protective sleeve or a gage block case away from abrasive materials.
