Row of nails where a number of nails 1 are interconnected by means of at least one connecting strip 2 such that the nails lie in parallel in a plane. The row of nails is characteristic in that the nail heads 4 have a conical underside and that the connecting strip(s) 2 are asymmetrically placed relative to the nailshafts such that the connecting strip only just encompasses said nailshafts at one side 5 while the connecting strip extends farther to the opposite side 3 of the nailshafts, at the latter side grooves are present in a driving tool for receiving said connecting strips with a certain play. A the driving in of a nail, its conical head 4 easily breaks the weak part 5a of the connecting strip. IMAGE
