Installation tool for an anchor element |
摘要 |
An installation tool for placing anchor elements includes an axially extending member and a ball with a thread on the member for engagement with the anchor element to be installed. The ball is captured in a receiving space in the installation tool and serves as a stop for limiting the threaded engagement of the tool with the anchor element. The ball has only a punctiform contact with the element, accordingly, the frictional engagement between the ball and the element developed while an anchor element is being screwed in is very small, so that the installation tool can be unscrewed easily from the anchor element after the element is installed.
