An interengaging fastener member having a plurality of headed elements, which can reduce the noise generated due to the relative movement between the headed elements engaged with each other. The fastener member 10 is made of polymeric material as a one-piece molded article, and includes a generally flat base 14 and a plurality of headed elements 18 projecting from the base 14. Each headed element 18 has a stem 22 arranged on and projecting from the base 14 in a predetermined spaced relationship, and a head 24 formed at the end of the stem 22 and having a contour swollen from the periphery of the stem 22. The head 24 is defined by a generally flat surface 26 adjacent t the stem 22 and extending radially outward from the periphery of the stem 22, a curved surface 28 bulging out with an apex and arranged at an opposite side of the generally flat surface 26 from the stem 22, and a transition surface 30 formed from a second curved surface for connecting the generally flat surface 26 with the curved surface 28.
