An expansion anchor sleeve has a leading end and a trailing end and can be inserted into an anchoring hole of a support structure. An expander member is located at the leading end and can be drawn into the same by a screw extending through the sleeve and engaging the expander member. A portion of the screw extends from the trailing end of the sleeve and out of the anchoring hole, being adapted to extend through an object that is to be secured to a support structure. A nut is threaded onto this portion and arranged to engage the screw after it has been threaded onto the same to some extent, so as to turn the screw and cause it to pull the expander member into the leading end of the sleeve, thereby expanding the same, until the nut finally contacts the object to be supported and holds the same in place. |
