  • Drive fastener
    Patent number: 4533288
    Abstract: A drive fastener designed to be hammered into penetrable material. One end of the drive fastener is split. The opposite end of the drive fastener contains threads. A pair of nuts are threaded together on the threaded end of the drive fastener to receive the impact of a hammering device for driving the fastener into penetrable material. When being driven, the split end spreads while penetrating to secure the fastener in place. The nuts are then removed and a single nut may be used to secure an object to the set fastener.
