ABSTRACT:
A new Double-Ended Nail Driving System for securing two boards together without scarring a surface of the boards by securing a conventional fastener into the surface of the boards. The inventive device includes a double-ended nail having a center flange, an elongated cylinder having an elongated cavity projecting into an end for removably receiving an end of the double-ended nail, and a lower flange attached to the end for engaging the center flange of the double-ended nail. The lower flange engages the center flange thereby allowing the user to tap upon an opposite end with a conventional hammer thereby penetrating the double-ended nail into the board within dulling a sharpened end of the double-ended nail. The present invention further reduces the amount of scarring normally associated with conventional fasteners securing the two boards together.
