Vermont Gage 141112850 Class X Plus Pin Gage 0.1285 in

Product Description

The VERMONT GAGE 141112850 is a Class X Plus precision pin gage manufactured from tool steel for direct part gaging and calibration of measuring equipment. This pin measures 0.1285 inches in diameter and 2 inches in length, held to a tolerance of +0.00004 inches — the tightest classification in the Class X Plus standard. The surface finish is held to 4 microinch, supporting accurate, repeatable contact measurement. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibration labs and quality-controlled production environments.

This pin gage is used in metrology labs, machine shops, and manufacturing facilities where precise hole and bore verification is required. It is appropriate for both go/no-go inspection workflows and direct measurement of machined parts. Calibration technicians and quality control inspectors use Class X Plus pins when the tightest dimensional tolerance verification is required. The 2-inch length provides adequate handle clearance for most benchtop and fixture-based applications.

Key Features

• Class X Plus tolerance of +0.00004 inches for highest-accuracy gaging
• Tool steel construction for durability and dimensional stability
• 4 microinch surface finish for consistent, low-distortion contact
• NIST-traceable Certificate of Accuracy included with each pin
• 0.1285 inch diameter, 2 inch length — ready for direct part or fixture use

Compatibility

Designed as an OEM-style replacement and standard precision tool for use in calibration systems and inspection setups requiring Class X Plus pin gages in the 0.1285 inch diameter range.

Installation Notes

Pin gages are handled and stored by calibration technicians and quality inspection personnel, not field tradespeople. Always handle pin gages with clean, lint-free gloves to prevent contamination or corrosion from skin contact. Store in the provided case when not in use to protect the lapped surface finish. Do not force pins into bores — if resistance is felt, stop and verify the bore dimension before proceeding.
