Abstract

System for driving av en skrue, innbefattende en skrue og et tilsvarende verktøy, hvor skruehodet har en heksalobeformet åpning (2) i skruehodets øvre flate, en øvre omkretsvegg (9) med heksalobeformet planform strekker seg ned i skruehodet, parallelt eller tilnærmet parallelt med skruens akse, en skrå overgangsflate (15) strekker seg nedover og innover i forhold til den øvre omkretsveggens (9) nedre kant, og en avsmalnende utsparing strekker seg nedover fra den skrå overgangsflatens (15) nedre kant, idet skruehodets dimensjoner er slik at når skruehodet påvirkes av et verktøy (6) med øvre (16) og nedre (17) samvirkeavsnitt, hvilket øvre samvirkeavsnitt (16) avsmalner nedover med en vinkel i forhold til aksen til den skruen som verktøyet skal samvirke med, og hvilket nedre samvirkeavsnitt (17) avsmalner nedover, vil det foreligge en "vedhengspasning" mellom overflaten i den avsmalnende utsparingen (11) og den ytre flaten til det nedre avsmalnende samvirkeavsnittet (17), og intet samvirke med den skrå overgangsflaten (15).
