A sleeve bolt for insertion in a hole delimited by a wall comprises a threaded fastener and an expansion member. The threaded fastener has a stem that includes a proximal cylindrical shank and a distal threaded section. The shank has substantially the diameter of the hole defines at a distal end thereof a conical expander portion. The expansion member comprises a distal threaded member and a proximal expansion wedge, the threaded member being threadably engaged to the threaded section of the stem. The expansion wedge has a proximal end adapted, upon axial displacement of the expansion member towards the shank resulting from a rotation of the stem, to engage the conical expander portion such as to expand the proximal end of the expansion wedge outwardly into engagement with the wall. The expansion wedge fractionally engages the wall upon introduction of the stem in the hole, whereas the threaded member is spaced from the wall. The threaded member comprises a distal conical section which tapers towards the expansion wedge and which is adapted to displace towards and relative to both the expander portion and the expansion wedge such that the conical section causes a distal end of the expansion wedge to expand outwardly into engagement with the wall.
