Abstract
A straddling dowel includes at least a pair of shell members each having a first contact surface and a second contact surface. The first contact surfaces are disposed in contact with one another and extend in parallel with the axis of the dowel and the second contact surfaces are disposed in contact with one another and extend helically relative to the axis of the dowel. The first and second contact surfaces extend for substantially the entire axial length of the shell members.
