摘要 |
<p>The threaded element with a tool attachment (5,6) has a spring element (8) seated on the periphery of the threaded element and consequently of the screw head (4) or threaded nut, radially protruding beyond the periphery, and forming a workpiece contact face (9) which lies outside the periphery and is concentric to the thread axis (7). The spring element is a ring with a continuous or discontinuous ring-form contact face. Independent claims are also included for the following: (a) a screw (1) with a head in the form of a threaded element which is thread forming or self-cutting; and (b) a threaded connection, whereby only the spring element with a predetermined pretensioning force lies upon the adjacent workpiece.</p> |
