A fastening device has a first fastening member with a plurality of teeth and a second fastening member with a plurality of sockets which are sequentially engagable in tooth and socket pairs in an engagement direction by relative rotation of the tooth and socket. Each tooth has a first surface and a second surface fixed relative to the first surface. Each socket has a recess defined by a first wall and second wall fixed relative to the first wall. Upon engagement, the first and second surfaces of the tooth abut the respective first and second walls of the recess and prevent relative movement of the tooth in the engagement direction and a portion of the first wall of the socket closely abutting the first surface of the tooth is disposed between the tooth and a portion of the first fastening member and prevents relative separation of the tooth and socket.

A slide fastener with which a slide fastener-attached product capable of preventing or suppressing exposure of a fastener tape can be manufactured is provided. The slide fastener includes fastener stringers and a slider, in which each of fastener elements includes an element base portion and a fin portion extending from the element base portion toward a tape inner side of a fastener tape and having a smaller dimension in a tape thickness direction than the element base portion, in which, at a shoulder-port-side end portion of a slider body, a leading end portion of the fin portion of each of the fastener elements is positioned on the outer side of the slider body with respect to an inner wall surface of a flange, and in which the ratio of a total fin width to an element maximum width is less than 40%.

A waterproof slide fastener with waterproof property in which covering the whole front and rear faces of a woven or knitted fastener tape with an elastomer, and fastener elements made of a thermoplastic resin are injection molded on the lateral edge of the fastener tape. In particular, a waterproof slide fastener that can maintain the watertightness and airtightness even when the fastener tape is bent in the lengthwise direction because, on the assumption that the minimum width between the outer end edges of the neck part of the fastener element in the lengthwise direction of the fastener tape that is a slide direction in which the slider slides is N and the width between the outer end edges of the body part of the fastener element in the same lengthwise direction is B, the value of B/N is between 2.5 and 3.5.

A zipper fastener system is provided for removably connecting separate structures. More particularly, a zipper fastener system is provided having connection sections attached to independent pieces that may be secured to and removed from each other utilizing two sliders, such that, when the connection sections are secured to each other, the two sliders permit an access opening of variable length and location along the connection sections and permit adjustments from either side of the zipper fastener system.

An apparatus including a first surface configured to attach the apparatus to a second surface of another object, and a plurality of elongated nanofibers. Each nanofiber has one end connected to the first surface and an opposite end extending away from the first surface. The plurality of elongated nanofibers is configured to adhere to the second surface by nanoadhesion when brought into contact with the second surface.

A fastener element for a slide fastener includes: a coupling portion; and one single root portion either including, or being plastically bendable to include, a bent portion and a distal end portion which extends from the bent portion towards a side of the coupling portion which is closer to the fastener tape. Each face of the coupling portion includes an engaging protrusion protruding in a lengthwise direction, and an engaging recess recessed in a lengthwise direction with respect to the face, and is configured for receiving an engaging protrusion of a fastener element on the opposite stringer in a closed condition of the slide fastener.
