Value Collection SF043027 Precision Dowel Pin 1/4x1/2 in Grade 8

Product Description

The VALUE COLLECTION SF043027 is a precision dowel pin engineered for accurate alignment and load transfer in mechanical assemblies. Manufactured from alloy steel to Material Grade 8, this pin measures 0.25 inches in diameter and 0.5 inches in overall length. It carries an ASME B18.8.2 fastener standard designation and achieves a Rockwell hardness of 50-58 HRC. One end is beveled and the other is rounded, supporting easy insertion and removal during assembly. Rated at 12,800 pounds breaking strength in double shear, it is suited for demanding load-bearing applications in industrial machinery, tooling fixtures, and precision equipment.

This dowel pin is used wherever tight-tolerance component alignment is required. Common applications include jigs, dies, mold bases, machine fixtures, and general industrial assemblies where repeatable part positioning is critical. The 0.0002-inch diameter tolerance ensures a controlled press or slip fit depending on the mating bore specification. Machinists, tool and die makers, and maintenance technicians working in manufacturing or fabrication environments typically source and install this type of fastener.

Key Features

• Alloy steel construction to Material Grade 8 for high strength and wear resistance
• Hardness rating of 50-58 HRC provides resistance to deformation under shear loading
• 12,800 pounds double-shear breaking strength for demanding load applications
• Diameter tolerance of 0.0002 inches supports tight-fit alignment applications
• One beveled end and one rounded end for controlled press-fit insertion
• Meets ASME B18.8.2 fastener standard for dimensional conformance

Compatibility

Designed as an OEM-style precision dowel pin compatible with bored holes meeting ASME B18.8.2 dimensional standards for 0.25-inch diameter precision pins.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using an arbor press or similar controlled force tool. Confirm bore diameter and tolerance before installation to avoid galling or damage to the mating component. Never drive precision dowel pins with an unguided hammer blow, as this can alter surface finish and compromise fit. Inspect the bore for burrs or debris before pressing the pin to its final seating depth.
