Claim 0:
1. A male touch fastener product, comprising
a resin surface;
an array of spaced-apart male touch fastener elements carried on the surface, each touch fastener element extending above the resin surface and comprising
an elongated stem extending from the surface and defining, at a midpoint of an overall length of the stem, an average lateral extent in a plane perpendicular to the stem; and
a head disposed at a distal end of the stem and forming with the stem and the surface a contiguous mass of resin, the head extending laterally from the stem to a distal edge overhanging the surface, the head defining an overall lateral extent at the distal edge, the fastener element having an average overhang defined as a difference between the overall lateral extent of the head and the average lateral extent of the stem;
wherein the fastener element head comprises
a central region that is generally flat and perpendicular to the stem and disposed directly above the stem; and
an edge region surrounding the central region, in which edge region the upper surface angles downward toward the resin surface, the edge region terminating at the distal edge of the head;

wherein the edge region of the upper surface of the head defines a declination angle with respect to the resin surface; and wherein for each of at least most of the fastener elements of the array, the declination angle of the edge region of the upper surface of the head at one side of the head is greater than at an opposite side of the head; and
wherein for each of at least most adjacent pairs of fastener elements of the array, the two heads of the fastener elements of the pair are separated by a lateral distance of between 2.0 and 7.0 times an average of the overhang of the fastener elements of the pair.
