摘要： A removable blind fastener includes an anti-rotation body having an external face with an aperture, the external face being suitable for engaging with a surface of a work-piece to be clamped. The fastener further includes a hollow leg member with a plurality of slots defining outwardly biasable resilient legs at one end and an externally threaded portion at the other end, the leg member having a bore tapering towards the legs, the leg member being translatable through the aperture, the leg member and the aperture further having inter-engaging anti-rotation features to prevent the leg member from rotating about its central axis relative to the anti-rotation body. The fastener may further include a thread tube with an internal thread cooperable with the external thread of the leg member and located co-axially with the leg member and a rod member having a shaft with a head end and a free end.

摘要： The present invention provides a removable blind fastener 2 having a first tubular element 4 comprising an arm portion 24, 26, 28, a second tubular element 6 comprising an arm portion 30, 31, 32, and an elongate screw member 8. The elements are arranged in telescoping relationship one with the other and which fastener, when in use as a temporary fastener, is caused to secure the component parts of an airframe by causing telescoping movement of the elements towards each other when the screw member is turned in one direction and is caused to release the component parts of the airframe by causing telescoping movement of the elements away from each other when the screw member is turned in an opposite direction. The arm portions of the elements are located in mutual juxtaposition for telescoping movement upon rotation of the screw member as aforesaid with end portions of elongate arms of the arm portions being brought into engagement with tapered sills 34, 36 of the first tubular element whereby the arms are caused to splay outwardly to bring the end portions into engagement with an underside 12a of the component and moving the component into secure temporary relationship with the component of the airframe.

摘要： A fastener includes a hollow tubular body, a hollow leg member translatable within the body having a plurality of resilient legs each with a head at the distal end for engaging with a work-piece. The fastener also includes an actuating member for biasing the resilient legs, where the actuating member includes a profiled tip, the profile of the tip includes a ramp for expanding the legs and a stop, and the stop and legs are arranged such that the stop can engage with an end surface of the legs to draw the legs further into the body and not bias the legs radially outward.

摘要： The present invention provides a removable blind fastener (2) having a first tubular element (4) comprising an arm portion (22), a second tubular element (6) comprising an arm portion (28), and an elongate screw member (8). The elements (4 and 6) are arranged in telescoping relationship one with the other and which fastener (2), when in use as a temporary fastener, is caused to secure the component parts (10 and 12) of an airframe by causing telescoping movement of the elements (4 and 6) towards each other when the screw member (8) is turned in one direction and is caused to release the component parts (10 and 12) of the airframe by causing telescoping movement of the elements (4 and 6) away from each other when the screw member (8) is turned in an opposite direction. The arm portions (22, 28) of the elements (4 and 6) are located in mutual juxtaposition for telescoping movement upon rotation of the screw member (8) as aforesaid with end portions (30a and 32a) of elongate arms (30 and 32) of the arm portions (22 and 28) being brought into engagement with a tapered portion (44) of the screw (8) whereby the arms (30 and 32) are caused to splay outwardly to bring the end portions (30a and 32a) into engagement with an underside (126) of the component (12) and moving the component (12) into secure temporary relationship with the component (10) of the airframe.

摘要： The present invention is concerned with improvements to removable fasteners and is particularly related to removable and re-usable fasteners for use in wet-fit applications, such as joining components that include a sealant or adhesive. A dowelling fastener (200) is provided having a head end and an insertion end and a cylindrical dowelling portion, wherein the fastener is provided with a plunger (204) at the insertion end for clearing material from a hole as the fastener is inserted into the hole, wherein the plunger is rigid and has a circular cross section with a diameter substantially the same as the dowelling portion of the fastener, the plunger tip thereby being a close fit with the hole. The plunger of the present invention is intended specifically for clearing materials from the bore and therefore has other features optimised for this purpose, including ridges around its periphery.

摘要： The present invention is concerned with improvements to removable fasteners and particularly relates to removable and re-usable fasteners with features that allow them to be gripped and handled positively. The present invention therefore provides a fastening system comprising a fastener and a tool, the tool being suitable for installing and removing the fastener from an aperture in a work-piece, wherein the fastener has a main body and a head at one end, and wherein the head of the fastener and the tool have grip features that allow the fastener to be releasably locked to the tool to prevent separation of the fastener and tool during installation and removal of the fastener. This allows the fastener to be handled positively without fear of the fastener becoming misaligned, or dropping off the tool.
