A fastening element (1) is provided having a gripping portion (5), a plurality of gripping elements (20, 20) extending from the gripping portion (5), a supporting portion (10) being defined by at least one supporting-portion wall extending from the gripping portion (5) in a direction opposite that of the gripping elements (20, 20), the supporting portion (10) having a supporting-portion width smaller than a gripping-portion width of the gripping portion (5), such that a top flange is formed by the gripping portion (5) relative to the supporting portion (10) on at least one side of the fastening element (1), and an anchoring portion (15) extending from a distal end of at least one supporting-portion wall and parallel to the gripping portion (5) so as to form a bottom flange relative to the supporting portion (10) on the at least one side corresponding to the top flange.

A fastening element is provided. The fastening element includes a gripping portion having a first face and a second face the first face of the gripping portion comprising a plurality of gripping elements, and an anchoring portion offset from the second face and extending parallel thereto so as to form a flange portion, wherein the flange portion comprises at least one chamfer located at a terminal section of the flange portion.

A surface fastener which includes a hook surface fastener (A) and a loop surface fastener (B), or a mixed surface fastener (C). The hook surface fastener (A) has hook fastener elements made of monofilaments on a surface of a base fabric. The loop surface fastener (B) has loop fastener elements made of multifilaments and capable of engaging with the hook fastener elements on a surface of a base fabric. The mixed surface fastener (C) has hook fastener elements made of monofilaments and loop fastener elements made of multifilaments on the same surface of a base fabric. The monofilaments are made from a polyethylene terephthalate-based polyester resin, and the multifilaments are made of a polybutylene terephthalate-based polyester resin.
