Bei den gebräuchlichen Plattenverschraubungen pflegt die Mutter an dem Bolzen anzurosten und ist dann nur schwer abzuschrauben. Um diesem Uebelstaride abzuhelfen, erhält nun der Bolzen α an Stelle des Kopfes beiderseitig zwei Ansätze c d, unter welche die beiden durch den Quertheil f mit einander verbundenen Krallenhaken e greifen und sich gleichzeitig oben an den Kopf legen. Durch Anziehen der Mutter b wird eine feste Verbindung hergestellt, welche jedoch auf einfache Weise gelöst werden kann, indem man eine Zange oder dergleichen beiy ansetzt und die Krallen unter dem Bolzenkopfe hervorzieht, worauf der Bolzen durch die etwas vergröfserten Löcher g nach unten fällt.In the case of common plate screw connections, the nut tends to rust on the bolt and is then difficult to unscrew. To remedy this starvation, instead of the head, the bolt α now has two attachments cd under which the two claw hooks e connected by the transverse part f grip and at the same time lie on top of the head. By tightening the nut b a firm connection is established, which can be easily loosened by using pliers or the like at y and pulling the claws out from under the bolt head, whereupon the bolt falls down through the slightly enlarged holes g.
