Abstract: A form stake having a narrow vertical shank body terminating at its upper end in a wider, flat driving shelf whose outer ends extend far enough from the shank body to provide grasping or hooking surfaces on the underside of the driving shelf spaced from the shank. At least a rearmost edge or surface of the shank is aligned flush with the rearmost edge of the driving shelf, allowing the entirety of the stake to be driven smoothly down into the ground adjacent the face of a form board. In a preferred form the stake includes reinforcing flanges extending from the underside of the driving shelf to an upper end of the shank, the flanges terminating short of the outer ends of the driving shelf.

Abstract: A form stake for use in securing wooden forms around an area of concrete to be poured. The stake has a flat body with a T-shaped flange structure protruding from its front face, while the rear face of the stake is flat to slide smoothly against the face of the form as the stake is driven into the ground. The T-shaped flange structure has a central vertical rib terminating at the upper end of the stake in a horizontal driving shelf centered over the vertical rib. The driving shelf has a flat, uniform upper driving surface that forms the uppermost end of the stake. The driving shelf terminates at the flat rear face of the stake so that its upper surface can be driven level with the upper edge of the form using any non-specialized driving tool, at which point the stake tends to level itself with the upper edge of the form without being unintentionally driven below the upper edge of the form.
