Abstract:

Disclosed and described herein is a nail extractor adapted for the powered extraction of partially exposed headed-nails from a substrate. The extractor has a housing with a threaded opening for the fitment of a threaded spindle having a hexagonally-shaped proximal end for the attachment of a power tool and a claw assembly attached to the distal end of the spindle so as to permit free rotation of the spindle while the claw assembly is confined and sized to prevent turning within the housing. Additionally, the claw assembly has a cleft for engaging and grasping the partially exposed portion of the headed nail. When activated by the powered tool, the threaded spindle and claw assembly are vertically elevated within the housing and the partially exposed nail is extracted from the substrate.
