ABSTRACT:
This invention provides a surface fastener of thermoplastic resin comprising, as integrally molded members thereof, a flat substrate and rows of large number of hooks standing from the substrate as engaging members and arranged continuously. The hooks of the surface fastener according to the invention hardly collapse, even if they are very small, and reliably come into engagement with mating loops of a matching surface fastener to provide a satisfactory engaging and peeling strength and a high ratio of engagement. The surface fastener according to the invention can endure repetitive engaging and disengaging operations. Each of the engaging elements has a stem, two or more than two necks extending radially in different directions from the stem and engaging heads substantially linearly extending from the stems in the different directions by way of the respective necks and each of the engaging heads has a cut-out formed at the remote end thereof transversally relative to the extending direction of the engaging head. Additionally, the top of the engaging head is substantially flat and the engaging head is tapered toward the front end thereof.
