A fastener extraction device includes a body configured for attachment to a power driver tool, and allows a rotating chuck provided thereby to extend therethrough. The extraction device includes a plurality of spring-biased grasping arms that are pivotably attached to the body and are moved between opened and closed positions by a actuation collar that is in operative engagement with the grasping arms. When the grasping arms are moved to a closed position, the extraction guides form an extraction aperture around the shank of the fastener below its head, allowing the operator to pull on the fastener using the leverage of the power driver tool to extract it from a surface in which it is embedded. Once the fastener is extracted, the actuation collar is rotated, so as to allow the grasping arms to move to an open position, whereupon the extraction guides release the fastener. |
