Abstract

Oppfinnelsen foreslår en skrue og en fremgangsmåte for tilvirkning av skruen, med hvilke den vanligvis glatte delen av skrueskaftet (2) mellom skruehodeenden (3) og skrugjengen (10) likeså stabiliseres ved hjelp av kalddeformering. For tilvirkning av en slik kalddeformering kan eksempelvis en flat gjengeprofil (6) påvalses. Likeså er en rilleprofil mulig. Med en sterkere preging av gjengeformen i holdeavsnittet (5) kan dette også anvendes for ved hjelp av innskruingsforløpet å trekkes inn i materialet, slik at det derved utelukkende skjer en lokalisering av holdeavsnittet. I dette tilfellet kan det unnlates et skrue-hode på skruen.The invention proposes a screw and a method for manufacturing the screw, with which the usually smooth part of the screw shaft (2) between the screw head end (3) and the screw thread (10) is likewise stabilized by means of cold deformation. For the manufacture of such a cold deformation, for example, a flat thread profile (6) can be rolled. A groove profile is also possible. With a stronger embossing of the thread shape in the holding section (5), this can also be used to be pulled into the material by means of the screw-in process, so that only a localization of the holding section takes place. In this case, a screw head on the screw can be omitted.
