Metal Anchors for Block and Brick
These anchors expand and distort when a screw is inserted to reinforce the hole and resist stripping. To install, drill a hole slightly deeper than the anchor is long and insert the anchor until it's flush with the surface. Then, thread a sheet metal or wood screw through your fixture and into the anchor. To determine screw length, add the anchor length to the fixture thickness and choose a screw longer than this. Pull-out strength values are 25% of the ultimate values.
