A sleeve bolt (A) for insertion in a hole
delimited by a wall comprises a threaded fastener
(10) and an expansion sleeve (12). The threaded
fastener (10) has a stem (14) that includes a
proximal cylindrical shank (16) and a distal threaded
section (18). The shank (16) has substantially the
diameter of the hole and defines at a distal end
thereof a conical expander portion (20). The
expansion sleeve (12) comprises a distal threaded
member (26) and a proximal expansion member (28), the
threaded member (26) being threadably engaged to the
threaded section (18) of the stem (14). The expansion
member (28) includes anchor legs (32) each having a
proximal end (38) adapted, upon axial displacement of
the expansion sleeve (12) towards the shank (16)
resulting from a rotation of the stem (14), to engage
the conical expander portion (20) such as to expand
the proximal ends (38) of the anchor legs (32) of the
expansion member (28) outwardly into engagement with
the wall. The expansion member (28) fractionally
engages the wall upon introduction of the stem (14)
in the hole.
