Abstract

En boltfesteanordning for å sentrere og holde fast en bolt i et bolthull, omfattende en kropp med en ytre overflate som strekker seg en lengde fra en anleggsflate til en entringsflate. Anleggsflaten har en større utstrekning enn entringsflaten, den ytre overflaten er tilveiebragt for anlegg mot bolthullets vegg, og et hulrom strekker seg i hele boltfesteanordningens lengde mellom anleggsflaten og entringsflaten og er innrettet for å oppta i det minste et parti av bolten.A bolt fastener means for centering and holding a bolt in a bolt hole, comprising a body with an outer surface extending a length from an abutment surface to an entrance surface. The abutment surface has a greater extent than the entrance surface, the outer surface is provided for abutment against the bolt hole wall, and a cavity extends throughout the length of the bolt fastener between the abutment surface and the entrance surface and is adapted to accommodate at least a portion of the bolt.
