A 3/4 inch nut driver is needed to drive the anchor. The 1/2 inch diameter, 3 inch long screw requires at least 2 inches of embedment, and fixture thickness must not exceed 1 inch. The fixture hole should be 9/16 inch in diameter, with minimum edge distance of 5 inches and center-to-center spacing of 8 inches.
