Value Collection 241382BR Precision Dowel Pin 5/8x2.5in Grade 8

Product Description

The VALUE COLLECTION 241382BR is a precision dowel pin used to locate, align, and secure mating components in machined assemblies. Manufactured from alloy steel at Material Grade 8, this pin meets ASME B18.8.2 dimensional standards and is hardened to 50-58 HRC for resistance to shear and wear in demanding applications. The 0.625-inch diameter pin measures 2.5 inches in overall length and holds a diameter tolerance of 0.0002 inches, making it suitable for tight-tolerance slip-fit and press-fit holes. Machinists, toolmakers, and precision assembly technicians install these pins in fixtures, dies, molds, and structural assemblies where repeatable part alignment is critical.

This dowel pin is appropriate for use in machine tool fixtures, jigs, dies, molds, and general precision assembly applications where accurate component registration is required. The one beveled end and one rounded end configuration aids insertion and reduces the risk of hole damage during assembly. This pin is sold individually with a minimum order quantity of 10 units per order.

Key Features

• Alloy Steel Grade 8 construction with 50-58 HRC hardness for high shear resistance
• ASME B18.8.2 compliant for standardized dimensional interchangeability
• Diameter tolerance of 0.0002 inches supports tight-tolerance precision fits
• One beveled end and one rounded end for controlled insertion and alignment
• Breaking strength of 79,800 pounds measured in double shear
• Compact 0.01-pound weight per pin simplifies handling in high-volume assembly work

Compatibility

Designed as a standard ASME B18.8.2 precision dowel pin for use in any application requiring a 5/8-inch diameter, 2.5-inch length press-fit or slip-fit locating pin in alloy steel.

Installation Notes

Precision dowel pins are typically installed by machinists or toolmakers using an arbor press or hydraulic press for press-fit applications; hand insertion with light mallet tapping may be appropriate for slip-fit applications. Verify hole diameter, depth, and surface finish against ASME B18.8.2 tolerances before installation. Do not force an oversized pin into an undersized hole, as this can damage the bore or fracture the pin. Wear appropriate eye protection when pressing or driving any hardened pin.
