Value Collection 241388BR Dowel Pin 5/8x3 in Alloy Steel Gr8

Product Description

The VALUE COLLECTION 241388BR is a precision dowel pin machined from Grade 8 alloy steel for use in high-load alignment and locating applications. The pin measures 0.625 inches in diameter and 3 inches in overall length, with a diameter tolerance of 0.0002 inches for tight-fit, repeatable positioning. One end is beveled for easy insertion and the opposite end is rounded. Hardness is rated at 50-58 HRC, giving the pin excellent resistance to shear and wear under cyclic loading. Licensed machinists, toolmakers, and maintenance mechanics typically specify this pin for jigs, fixtures, dies, and precision-machined assemblies.

This dowel pin suits industrial and manufacturing environments where exact part registration is required. Typical applications include aligning mold halves, fixture plates, machine bases, and bearing housings. The Grade 8 alloy steel construction and ASME B18.8.2 compliance make it suitable for both original equipment builds and maintenance repair scenarios. The pin is sold individually per package, with a minimum order quantity of 5 units, making it practical for bench stock and scheduled maintenance programs.

Key Features

• Grade 8 alloy steel construction rated at 50-58 HRC hardness for high shear resistance
• 79,800 pound double-shear breaking strength for demanding load applications
• Diameter tolerance of 0.0002 inches for precision locating and repeatable alignment
• One beveled end and one rounded end for controlled insertion and retention
• Manufactured to ASME B18.8.2 standard for dimensional consistency
• Compact at 0.26 pounds per pin, suitable for lightweight fixture and tooling assemblies

Compatibility

Designed as a standard-dimension precision dowel pin per ASME B18.8.2, suitable for any application requiring a 0.625-inch diameter by 3-inch length locating pin in alloy steel.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using a press or arbor press to seat the pin in a reamed hole sized to the appropriate interference or transition fit. Power down and de-energize any machinery before pressing or removing pins in operational equipment. Avoid driving pins with a hammer directly on the pin face, as this can damage the precision ground surface and alter the fit. Confirm hole depth and pin length before pressing to prevent bottoming damage.
