A pin has a pilot point of uniform width throughout 360.degree. and a body containing a cross section of arcuate polygonal lobular configuration, also of uniform width but wider than the point. The pin may be driven into a circular hole in a member such that the lobes of the pin are elastically deformed in compression to enhance the grip between the pin and the member and with there being regions of stress relief on the member intermediate the lobes. The hole in the member may also be reshaped into a lobular form. The uniform body width approximates the minimum diameter of the hole in the member. Furthermore, the pin is of a range of lobulation sufficient to span a wide range of hole diameter tolerances.
