    Default Wedge Expansion Anchor (Bolt)

    Question: can wedge expansion expansion anchor bolts be uninstalled (removed).

    I am securing a fire safe (60" H, 435 lbs) to my garage floor -- manufacturer recommends 4 "wedge anchors" of minimum 3" long & 9/16" dia.

    Once installed, can the anchors be "unexpanded" for removal, to move the safe ??

    I suppose I can buy 4, hand tight one a little, and reverse it to see of the wedge elbow retracts. . .

    Generally, no, the wedges do as they are supposed to and secure the bolt in the hole, what you can do is simply cut them off and leave it or tap the bolt shank down into the hole and fill with a bit of mortar.

    You see them on city concrete sidewalks, in places where they used to have newsstands or mail boxes which were removed. The bolts cut off and ground to the concrete.

    How about Tapcon concrete/masonry screws ? I have never used them, and don't know if they come in the size needed, especially the diameter.

    Anyone unscrewed them ?

    Thanks.
