Screw bolt for connecting e.g. metal structures, has cone screwed by pitch of external thread and internal thread, where locking of locking heads takes place mechanically via rotary handle and threads
摘要
<p>The screw bolt has a cone screwed by a pitch of an external thread (2) and an internal thread (6) in a sleeve (4) against locking heads (7), where locking of the locking heads takes place mechanically via a rotary handle (3) and the external and internal threads. The locking of the bolt is carried out against the sliding out of the bolt with the locking heads in the shape of a pin or a ball. A connection between the sleeve and the bolt with the cone exhibits a threaded connection.</p>
