Value Collection 241004PR Precision Dowel Pin 1/16 X 1/4 in Alloy

Product Description

The VALUE COLLECTION 241004PR is a precision dowel pin used to align, locate, and retain mating components in assemblies requiring tight positional accuracy. Manufactured from alloy steel at Material Grade 8, it measures 1/16 inch in diameter and 1/4 inch in overall length. The pin carries a hardness rating of 50-58 HRC and a double-shear breaking strength of 800 pounds, making it suitable for high-load alignment applications. One end is beveled for easy insertion and the other is rounded. It conforms to ASME B18.8.2 standards. Machinists, tool-and-die makers, and mechanical assemblers install these pins in precision fixtures, jigs, and machine components.

This pin is intended for use in precision machined assemblies where repeatable alignment and tight tolerances are required. The diameter tolerance is held to 0.0002 inches, supporting consistent fit in reamed or bored holes. Typical applications include fixture building, die sets, mold alignment, and general industrial assembly work. The compact 1/4-inch length suits shallow-hole installations in tooling plates and machine frames. Minimum order quantity is 100 pieces; each package contains 1 piece.

Key Features

• Grade 8 alloy steel construction for high strength and wear resistance
• Diameter tolerance of 0.0002 inches for precise, repeatable fit in reamed holes
• 50-58 HRC hardness for resistance to deformation under load
• Double-shear breaking strength of 800 pounds
• One beveled end and one rounded end for guided installation
• Conforms to ASME B18.8.2 fastener standard

Compatibility

Designed as a standard ASME B18.8.2 precision dowel pin for use in any application requiring a 1/16-inch diameter dowel hole with a 1/4-inch depth of engagement in alloy steel or compatible tooling materials.

Installation Notes

Precision dowel pins are installed by machinists and toolmakers using a press or mallet into holes that have been finish-reamed to the correct tolerance. Verify hole depth and diameter before pressing the pin to avoid splitting the workpiece or damaging the pin. Always de-burr and clean the mating hole prior to installation. Pins should not be driven into holes that have not been properly sized, as this can compromise alignment accuracy and break the pin.
