An external surface for a fastener insert to be embedded in a component includes a plurality of spaced rings surrounding a embeddable shank of the insert. The rings define a plurality of waves. The ring height can be increased progressively from a distal end of the insert to the rings nearest the head of the insert, thereby providing a generally tapered outer configuration for the insert.

An aircraft component includes an exterior surface exposed to external airflow during flight, an interior surface, and a locally thickened fastening portion between the exterior and interior surfaces. An area of the interior surface on the locally thickened fastening portion is substantially parallel to an area of the exterior surface on the locally thickened fastening portion. The thickness of the aircraft component between the exterior surface and the interior surface is greater at the fastening portion than at an area surrounding the fastening portion. When the additional component is fastened to the substantially parallel area of the interior surface on the fastening portion with mechanical fasteners, the mechanical fasteners do not penetrate the exterior surface.

A wooden member joint structure having high strength against load repeatedly applied in opposite directions, with improved work efficiency in joining the wooden member to a mating member. A screw member having spiral protrusion on its outer peripheral surface and an axial hollow hole is threaded axially into a wooden column. A distal end of joint bolt is threadedly engaged with bottom of the hollow hole. The joint bolt has an integrally formed flange, and the flange is threaded into the column together with the screw member with its contact surface firmly pressed against end face of the screw member. A joint device is clamped between a fastening nut threadably mounted on a proximal end of the joint bolt and the flange and coupled to the screw member via the joint bolt. The joint device is secured to a foundation by an anchor bolt protruding therefrom and a fastening nut.

An element with a shank (1) and a holding element (2) connected to it for connecting to a rod (100) is provided, wherein the holding element (2) has a recess (3) having a U-shaped cross-section for receiving the rod (100) with two legs (4, 5) open at one end (6) and an inner thread (7) on the open legs (4, 5) and a locking element (9) with an outer thread (8) which cooperates with the inner thread of the legs, wherein the inner thread (7) of the legs and the outer thread (8) of the locking element are constructed with a flat thread in which the two flanks (7a, 7b; 8a, 8b)) enclose an angle of 90° in each case with the screw axis (S, M). This prevents splaying of the open legs when the locking element is screwed in. The flat thread is easy to produce.
摘要:
A fastening apparatus is provided to secure a first component to a second component. The fastening apparatus includes a fastening anchor and a securing member. The fastening anchor includes two separated securing parts defining internal screw thread and external screw thread. The securing member defines external screw thread. The securing member is accommodated into the fastening anchor by the securing member external screw thread engaging the fastening anchor internal screw thread, and the two separated securing parts of the fastening anchor is urged to expand outward to engage with one of the first component and the second component.
摘要:
A screw anchor for fastening add-on parts in concrete or brickwork comprising a shaft (10), which encompasses a thread, is characterized in that the external thread is embodied at a spiral (15), which is embodied separately from the shaft (10) and in that the spiral is connected to the outer periphery of the shaft in a positive manner.

A method of installing panels includes temporarily securing un-upholstered panels in place on an underlying support and marking the underlying support at each of a plurality of panel clip locations on the panel. The panel is removed from the support structure for upholstering. The support structure is drilled at the marks to provide a hole to receive a socket component, and a socket component is driven into each of the receiving holes in the support structure. The socket component includes a cup open to at least one end, an external thread for engaging the support structure, and a constriction in the cup spaced away from the bottom of the cup. A plug component is secured at each of the panel clip locations on the panel, the plug component having a protruding portion to engage in the socket. The upholstered panel is lifted into position and the periphery is pressed into place to engage the protruding portions of the plug components within the cups of the sockets.
