Value Collection 241085PR Precision Dowel Pin 1/8x3/8 in Grade 8

Product Description

The VALUE COLLECTION 241085PR is a precision dowel pin designed for accurate alignment and location of mating components in mechanical assemblies. Manufactured from Grade 8 alloy steel, this pin measures 1/8 inch in diameter and 3/8 inch in overall length. It carries a Rockwell hardness rating of 50-58 HRC, giving it the wear resistance required for tight-tolerance applications. The pin conforms to ASME B18.8.2 standards, ensuring dimensional consistency across production runs. One end is beveled for ease of insertion, and one end is rounded. Machinists, toolmakers, and maintenance technicians working on jigs, fixtures, dies, and precision assemblies rely on this type of pin for repeatable registration.

This pin is suited for use in industrial and manufacturing environments where accurate part alignment is critical. Typical applications include fixture building, die sets, mold alignment, and general machine assembly where a controlled-fit dowel is required. The 1/8 inch diameter and 3/8 inch length make it appropriate for compact assemblies and tooling with limited real estate. The Grade 8 alloy steel construction handles high shear loads in both light production and heavy-duty tooling contexts. It is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stock and production procurement.

Key Features

• Grade 8 alloy steel construction with 50-58 HRC hardness for wear and shear resistance
• Conforms to ASME B18.8.2 for dimensional and tolerance compliance
• Diameter tolerance of 0.0002 inches for precision fit in close-tolerance bores
• 3,200 pounds double-shear breaking strength
• One beveled end and one rounded end for guided insertion and flush seating
• Compact 1/8 x 3/8 inch size suits tight-space fixture and tooling applications

Compatibility

Designed as an OEM-style precision locating pin for use in mechanical fixtures, dies, molds, and assemblies requiring ASME B18.8.2 compliant dowels in a 1/8 inch diameter bore.

Installation Notes

Precision dowel pins are typically pressed or driven into reamed holes by machinists or tool and die technicians using an arbor press or appropriate driving tool. Ensure the receiving bore is reamed to the correct tolerance before installation. Never force a pin into an undersized bore with an impact hammer, as this can damage the bore or compromise pin geometry. Follow applicable shop safety procedures and de-energize or lock out any equipment before installing or removing pins from active tooling or machinery.
