Earth-boring tools carrying formation-engaging structures

An earth-boring tool, comprising:

• at least one blade located on a body of the earth-boring tool;
• cutting elements positioned in respective cutting element pockets on an exposed outer surface of the at least one blade, wherein the cutting elements comprise a polycrystalline diamond compact;
• a pocket opening onto the exposed outer surface of the at least one blade;
• a tapped bore extending through the at least one blade from at least one of a rotationally leading surface and a rotationally trailing surface of the at least one blade to the pocket, the rotationally leading surface being a leading surface of the blade as the at least one blade rotates around an axis of rotation of the body of the earth-boring tool, the rotationally trailing surface being a trailing surface of the blade as the at least one blade rotates around the axis of rotation of the body of the earth-boring tool;
• a formation-engaging structure received within the pocket of the at least one blade, the formation-engaging structure positioned intermediate at least two cutting elements along a radial axis of the body of the earth-boring tool, the formation-engaging structure having a distal end, a proximal end and a sidewall therebetween, and the distal end of the formation-engaging structure having a formation-engaging surface;
• a receiving formation located in the sidewall of the formation-engaging structure;
• and
• a threaded fastening element threaded within the tapped bore extending through the at least one blade, the threaded fastening element threadably engaging threads of the tapped bore, a first end of the threaded fastening element engaging the receiving formation of the formation-engaging structure, the threaded fastening element, as engaged, configured to retain the formation-engaging structure within the pocket of the at least one blade.
