Abstract
An expansion dowel includes an axially extending sleeve with an axially extending slot in the sleeve. The sleeve has protrusions extending generally circumferentially around and outwardly from the outer surface of the sleeve. At least some of the protrusions are formed each about a central axis extending at an acute angle to the axis of the sleeve. Adjacent pairs of the protrusions are located in planes which intersect on one side of the axis of the sleeve.
