Abstract

En løsnesikker bolt bestående av to deler (2, 3) som kan skilles fra hverandre i en,.tiltrukket mutter (7). Et innvendig gjenget hull (4) med liten diameter er utboret i en av de to boltdeler, mens et utvendig gjengeparti (5) med liten diameter er utformet på den annen boltdel. Det utvendige gjengeparti med liten diameter innskrues i det innvendig gjengede hull med liten diameter slik at der dannes en komplett bolt-enhet. Et inngrepsorgan (11) for omdreining av bol-. ten er utformet på boltenden'.A detachable bolt consisting of two parts (2, 3) which can be separated from each other in a tightened nut (7). A small diameter inner threaded hole (4) is drilled in one of the two bolt parts, while a small diameter outer threaded portion (5) is formed on the other bolt part. The small diameter outer threaded portion is screwed into the small diameter inner threaded hole to form a complete bolt assembly.
