Vermont Gage 141215800 Class X Minus Pin Gage 0.158 in

Product Description

The VERMONT GAGE 141215800 is a Class X Minus pin gage used to verify bore diameters, hole sizes, and feature locations to tight tolerances in precision machining and metrology applications. It measures 0.158 inches in diameter and 2 inches in length, with a tolerance of -0.00004 inches, placing it in the Class X Minus category for high-accuracy go/no-go and direct part gaging. The body is machined from tool steel with a 4 microinch surface finish. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented quality control workflows.

This pin gage is suited for calibration labs, machine shops, quality control departments, and toolrooms where close-tolerance hole verification is required. It is used to directly gage drilled, reamed, or bored holes and to calibrate or verify measuring equipment such as bore gages, air gages, and CMM fixtures. The 0.158-inch diameter makes it appropriate for small-bore inspection tasks common in precision manufacturing, aerospace component inspection, and hydraulic or pneumatic fitting verification.

Key Features

• Class X Minus tolerance of -0.00004 inches for high-precision go/no-go gaging
• Tool steel construction for hardness and dimensional stability under repeated use
• 4 microinch surface finish for accurate, low-friction bore contact
• NIST-traceable Certificate of Accuracy included for quality documentation
• Compact 2-inch length suitable for bench and inline inspection use

Compatibility

Designed as an OEM-style precision measurement tool for use in any application requiring direct hole gaging or calibration of measuring equipment to 0.158-inch nominal diameter.

Installation Notes

Pin gages are handled and used by metrology technicians and quality control personnel. Store in a dry, temperature-stable environment to prevent dimensional drift from thermal expansion. Handle with clean cotton gloves or lint-free cloth to avoid corrosion from skin oils. Do not force-fit the pin into a bore; light hand pressure is the correct technique for accurate readings.
