Value Collection 241451BR Precision Dowel Pin Alloy Steel

Product Description

The VALUE COLLECTION 241451BR is a precision dowel pin machined from alloy steel to Grade 8 specifications and certified to ASME B18.8.2 standards. It measures 0.875 inches in diameter and 2.5 inches in overall length, with a diameter tolerance held to 0.0002 inches for accurate alignment and tight-tolerance assembly work. One end is beveled for easy insertion; the opposite end is rounded. Hardness runs 50-58 HRC, providing resistance to wear and deformation under load. Breaking strength is rated at 156,000 pounds in double shear. Machinists, toolmakers, and maintenance technicians use this pin to locate and align mating components in jigs, fixtures, dies, and machinery assemblies.

This dowel pin is suited for industrial and manufacturing environments where consistent, repeatable component alignment is critical. Typical applications include fixture building, press tool assembly, machine component alignment, and die construction. The Grade 8 alloy steel construction makes it appropriate for high-load, high-cycle installations where a mild steel or unhardened pin would fail prematurely. It is sold individually and is compatible with standard 0.875-inch reamed or ground holes machined to close tolerances.

Key Features

• Diameter tolerance of 0.0002 inches for precise interference or transition fits
• 50-58 HRC hardness for wear resistance and structural integrity under load
• Breaking strength of 156,000 pounds measured in double shear
• One beveled end and one rounded end for guided installation
• Meets ASME B18.8.2 fastener standard
• Grade 8 alloy steel construction for demanding industrial service

Compatibility

Designed as a standard precision dowel pin for use in any application requiring an 0.875-inch diameter pin conforming to ASME B18.8.2 dimensional and tolerance requirements.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a hydraulic or arbor press. The receiving hole must be reamed or ground to the appropriate tolerance to achieve the intended fit class before pressing the pin into place. Never drive precision dowel pins with a hammer, as this can damage the pin surface or distort the hole geometry. Ensure all machinery is de-energized and locked out before disassembling or reassembling components that incorporate dowel pins.
