| 摘要 |
The present invention relates to a system for fastening a first structure to a second structure comprising a fastener having a head disposed at a proximal end of a shaft and a pointed tip disposed at a distal end of that shaft, and a plastic sleeve surrounding a portion of the shaft in coaxial-relation thereto. In a preferred embodiment, the first structure is a metal floor panel having means for receiving the fastener and the sleeve. The receiving means keeps the sleeve in substantially perpendicular-relation to a support portion of the second structure, with the pointed tip of the shaft disposed adjacent to the support portion. In this arrangement, when a driving force is applied to the head of the fastener, the fastener moves axially relative to the sleeve through the first structure into engagement with the second structure.
