The first engaging surface can have shape selected from cylindrical, ellipsoidal, conical, elliptic conical frustum, pyramidal frustum, and ball and other shapes having cross-sections of rectangular, pentagonal, hexagonal, octagonal and other regular polygons having at least four sides such that good engagement is obtained and the fastener is hidden from view in the assembled railing.
