Value Collection DP416-312-562 Precision Dowel Pin

Product Description

The VALUE COLLECTION DP416-312-562 is a precision dowel pin manufactured from Grade 416 stainless steel with a passivated finish. It measures 5/16 inches in diameter and 9/16 inches in overall length, with a diameter tolerance of 0.0000 to 0.0002 inches for tight, repeatable locating accuracy. The beveled end aids alignment during assembly. Hardness ranges from 36 to 42 HRC, giving the pin resistance to wear and deformation under load. Machinists, toolmakers, and maintenance technicians use this type of pin in fixtures, jigs, dies, and precision assemblies where consistent part location is required.

This dowel pin is suited for industrial and manufacturing environments where corrosion resistance and dimensional precision are both required. The Grade 416 stainless steel construction makes it a practical choice for applications exposed to moisture or mild chemical environments. The passivated finish, applied to ASTM A380-88 standards, removes surface contaminants and enhances the corrosion resistance of the base material. Typical applications include machine tool fixturing, mold and die alignment, and precision mechanical assemblies in light industrial settings.

Key Features

• Grade 416 stainless steel construction for corrosion resistance in demanding environments
• Passivated finish per ASTM A380-88 for enhanced surface protection
• Diameter tolerance of 0.0000 to 0.0002 inches for precision locating fitment
• Hardness of 36 to 42 HRC for wear resistance under repeated use
• Beveled end for guided insertion and ease of assembly
• UNSPSC Code 31163203 for streamlined procurement classification

Compatibility

Designed as a precision locating pin for use in fixtures, jigs, dies, and mechanical assemblies requiring a 5/16-inch diameter dowel hole with close tolerance fitment.

Installation Notes

Precision dowel pins are typically installed by machinists or toolmakers using an arbor press or similar controlled-force tool. The mating hole should be reamed to the appropriate tolerance class to achieve the intended interference or transition fit. Never drive a precision dowel pin with an impact tool, as this can damage the pin surface or distort the hole geometry. Ensure mating surfaces are clean and free of burrs before installation.
