Value Collection 241355PR Dowel Pin 1/2x3.5 in Alloy Steel Gr8

Product Description

The VALUE COLLECTION 241355PR is a precision dowel pin manufactured from Grade 8 alloy steel, designed for accurate alignment and positioning of mating components in mechanical assemblies. The pin measures 1/2 inch in diameter and 3-1/2 inches in overall length, with a tight diameter tolerance of 0.0002 inches for precise hole-to-pin fit. One end is beveled and one end is rounded per standard configuration. Hardness runs 50-58 HRC, giving this pin excellent resistance to shear loads and wear. Machinists, tool and die makers, and maintenance technicians install these pins where repeatable, exact part registration is required.

This dowel pin is suited for use in jigs, fixtures, dies, molds, and machine tool components where consistent alignment between two or more mating parts must be maintained across repeated assembly and disassembly cycles. It is appropriate for both original equipment manufacturing and MRO replacement applications in industrial, production, and maintenance environments. Conformance to ASME B18.8.2 makes it a direct fit for applications requiring that fastener standard. The minimum order quantity for this pin is 25 pieces.

Key Features

• Grade 8 alloy steel construction with 50-58 HRC hardness for high shear strength and wear resistance
• Diameter tolerance of 0.0002 inches for precise interference or slip fits in reamed holes
• 51,000 pounds breaking strength measured in double shear
• One beveled end and one rounded end for guided insertion and positive seating
• Conforms to ASME B18.8.2 fastener standard
• 1/2 inch diameter x 3-1/2 inch overall length

Compatibility

Designed as an OEM-style and MRO replacement precision dowel pin for mechanical assemblies requiring ASME B18.8.2 compliant 1/2 inch diameter pins.

Installation Notes

Precision dowel pins are installed by machinists and maintenance technicians using a press or mallet into reamed holes sized for the required fit class. Power down and de-energize all equipment before servicing any assembly containing dowel pins. Do not drive pins into drilled-only holes — holes must be finish-reamed to the appropriate tolerance to achieve the intended fit. Follow applicable machinery safety standards and facility lockout/tagout procedures during installation or removal.
