A wall anchor assembly (10) has a collar (20) from which a pair of posts (26) extend. A bolt (18) can pass through the collar. An anchor member (31) is captive between the two posts. Ridges and channels slidable engage the anchor member with its longitudinal axis substantially parallel to the posts and transmit axial rotation from the collar to the anchor member. The anchor member has a tip for tapping through a wall and ramps for rotating the anchor member perpendicular to the posts. Screwing the bolt draws the anchor member against the wall to clamp the wall anchor assembly to the wall.
