Fastener for securing a structural component to a carpet pad |
摘要 |
A fastener is formed with an elongated threaded portion defined by a central shank and a thread formed on the shank, a neck collinear with the shank, and a head provided with a recess adapted to receive a tool for rotating the fastener. The shank of the threaded portion includes a cylindrical body and a tapered penetrating point extending longitudinally from the body. The thread is provided with a constant diameter section along the cylindrical body and a tapered section along the tapered penetrating point. The constant diameter section defines a major diameter that is more than about double the minor diameter defined by the body of the shank. The thread defines a pitch greater than the cross-sectional thickness of the thread along the shank so that the cylindrical shank is exposed within each pitch of the thread. |
