A self-engaging fastener has a flexible base sheet and an array of discrete fastener elements projecting from a broad side of the base sheet. Each fastener element has a stem extending from the base sheet and a head at a distal end of the stem, the head overhanging the base sheet on multiple sides of the stem. The heads of the discrete fastener elements are arranged in a pattern of hexagonal groupings of fastener element heads bordering central regions void of fastener element heads, with each fastener element head spaced from edges of the array being part of three adjacent groupings. The product features a particularly high separation resistance for the area of the product covered by the heads.

Article includes: male and female fastening parts secured onto separate locations on the article, the male and female fastening parts being mutually engageable; and at least one article component having a nappable region with which the male fastening part is brought into contact at least partially. The male fastening part includes a multiplicity of male engagement elements where male engagement elements are two-dimensionally arranged, the multiplicity of male engagement elements including two or more male engagement elements each having a top surface that is brought into contact with the nappable region. The respective ones of the male engagement elements of the multiplicity of male engagement elements or of the two or more male engagement elements are made of a same polymer material having a bend elastic constant of 800 MPa or less, or 500 MPa or less, or 450 MPa or less.
