A shaft depressor is used for seating a shaft against a closed, usually curved, portion between first and second sides of a U-shaped socket in a slap yoke of a steering shaft assembly. It is used together with a clamp bolt which extends through a hole in the first side of the socket and fastens to threads at a second parallel side thereof. The shaft depressor consists of a cylindrical body having an inside diameter sized to fit over the clamp bolt, an outside diameter sized to pass through the hole in the first side of the U-shaped socket, and projecting members for pressing the shaft into the closed portion of the socket. The shaft depressor has a tapered lead at one end for easy insertion through the hole in the first parallel side and a plurality of fins projecting radially outwardly from the surface of the cylindrical bushing. The radially projecting fins may be axially extending ridges, circumferential ridges, cones, or a single helical ridge on the surface of the cylindrical body.
