Abstract

Abstract A screw package is provided formed of at least two stiff friable membranes arranged in spaced parallel relation each having aligned holes therein. The holes in one of the membranes being shaped to receive the head of a screw and the holes in the other membrane being adapted to receive the tip of a screw. A screw is inserted longitudinally through each pair of aligned holes with its head resting in the shaped hole of one of the membranes and its tip projecting through the other membrane. The heads of the screws are secured in position by a fluid bonding agent which is applied in the fluid state and then hardened. The membranes are sufficiently friable to permit the screws to be singly removed from the membranes as the screw is driven to apply it by the rotating motion of a driving means, such as a screwdriver.
