Summary: | A straddling dowel is formed of a metal sleeve having a continuous bore from its trailing end to its leading end. Axially extending slots are formed in the sleeve for a portion of its axial length extending from the leading end. Within the sleeve an axially extending portion of its bore surface, extending from the leading end, is tapered in diverging relationship toward the trailing end. The outer surface of the sleeve is free of grooves in the spreading range and a portion of the outer surface in the spreading range, extending axially from the leading end, is tapered. At the trailing end of the sleeve, its outer surface has a frusto-conical shape widening toward the trailing end. A member is insertable into the bore of the sleeve for spreading it and the spreading member has a frusto-conically shaped portion directed toward the leading end of the bore. |
