Abstract
An assembled sucker rod includes a rod body with a rod end and an endpiece containing a receptacle at the rod end. An adhesive is set between the receptacle and rod end, and an insert is positioned through the endpiece's side, contacting the rod end, and resisting compressive loads. The endpiece has apertures for the insert, which has ends and an intermediate portion; the latter contacts the rod end compressively, while the ends contact the endpiece oppositely. The rod end may feature a hole or slot for the insert, or its distal portion may directly abut the insert.
