Value Collection 241394BR Precision Dowel Pin 5/8x3.5in Grade 8

Product Description

The VALUE COLLECTION 241394BR is a precision dowel pin machined from alloy steel to Grade 8 specifications and certified to ASME B18.8.2. It measures 0.625 inches in diameter and 3.5 inches in overall length, with a tight diameter tolerance of 0.0002 inches for accurate, repeatable location in precision assemblies. Hardness is rated at 50-58 HRC, giving the pin strong resistance to wear and deformation under load. One end is beveled for easy insertion and one end is rounded. Breaking strength is rated at 79,800 pounds in double shear. Machinists, toolmakers, and mechanical assembly technicians install these pins to align fixtures, jigs, dies, and machine components.

Precision dowel pins of this diameter and length are commonly used in industrial and manufacturing environments where tight positional tolerances are required between mating components. Typical applications include die sets, mold bases, machine tool fixtures, and structural assemblies requiring reliable, repeatable part location. These pins are pressed or slip-fitted into reamed holes and are not intended for light-duty or non-precision applications. They are sold individually with a minimum order quantity of 10 units.

Key Features

• Alloy steel construction with 50-58 HRC hardness for wear resistance and load capacity

• 79,800-pound breaking strength measured in double shear
• One beveled end and one rounded end for controlled installation direction
• Meets ASME B18.8.2 fastener standard for dimensional consistency
• Grade 8 material grade for high-strength precision fastener applications

Compatibility

Designed as an OEM-style precision locating pin for use in reamed holes requiring a 0.625-inch nominal diameter precision dowel per ASME B18.8.2 standards.

Installation Notes

Precision dowel pins are installed by machinists or mechanical assembly technicians using a press or mallet into holes reamed to the appropriate tolerance class. Always verify hole diameter and finish before installation to avoid galling or damage to the pin or bore. Do not hammer pins into undersized or unreamed holes. Follow applicable machinery and tooling safety procedures when pressing or extracting hardened pins.
