A self-aligning aircraft door stop pin assembly, which minimizes galling and compensates for misalignment problems. The assembly consists of a base pad containing a concave spherical recess, which is swaged onto the convex spherical head at one end of a threaded stop pin. The base pad is free to align, so as to make full face contact with the structural stop pad. The sperical interface between stop pin and base pad is provided with lubrication, on one or both parts.
