摘要： A method of self-piercing riveting comprising inserting a self-piercing rivet (15) into a workpiece consisting of at least two layers (10, 11) of overlapping material such that the end of the rivet is deformed during the riveting process and remains encased in the material furthest from the point of impact of the rivet (15), characterised in that during at least part of the riveting process the sides of the rivet (15) are constrained against radially outward deformation in the region where the rivet enters the workpiece.

摘要： An insert (11) for installation in a relatively thin or weak workpiece (49) to provide an anchor for a self-tapping screw (48) or the like, which insert is in the form of an integral metal structure having a body portion, a head portion located at or near one end of the body portion and extending radially therefrom a receptacle portion located at the other end of the body portion remote from the head portion; and a through bore extending throughout the head, body and receptacle (25) portions the interior bore of the receptacle portion being substantially unthreaded for the reception of a self-tapping screw of the like the exterior cross-sectional shape and dimensions of the receptacle portion, and the interior cross-sectional shape and dimensions of the body portion, respectively being such that the body portion is deformable, when the receptacle portion is drawn towards the head portion, to secure the insert in a suitable hole in a workpiece through which the receptacle and body portions have been inserted so that the head portion is adjacent the workpiece and a substantial length of the body portion protrudes beyond the workpiece such that the part of the body portion nearer the receptacle portion enters inside the part of the body portion nearer the head thereby to enhance the engagement of the deformed body portion with the workpiece.

摘要： A method of blind riveting to secure together a plurality of members (26, 27, 28) with aligned apertures, using a blind rivet comprising a tubular shell (11) with a head (13) and a stem (12) extending through the tubular shell. The method comprises the steps of: inserting the shell through the aligned apertures, from the near face of the near member, so that the remote end of the shell protrude beyond the remote face of the remote member and the nearest end of the shell is substantially level with the near face of the near member; supporting the near end of the shell while pulling the stem head to form a remote blind head; applying a force to the near member with respect to the stem, until any gap (28) between the members is taken up and deforming the now protruding portion of the shell to form a near-side head of the rivet. The invention also encompasses a blind riveting apparatus and blind rivets for carrying out the method described above.

摘要： A sealing plug for blind installation in a suitable hole thereby to plug and seal the hole, which sealing plug has a sleeve (1); a stem (2) having a head at least part of which is radially enlarged with respect to the remainder of the stem (2); the stem head (4) having a shoulder, the shoulder being provided with an annular protrusion (9); the stem (2) protruding from one end of the sleeve (1), and the annular protrusion (9) abutting the other end of the sleeve (1); the stem head (4) being of a material which is harder than that of the sleeve (1) and being formed with a weakened portion (3) intermediate the head (4) and the part of the stem remote therefrom; whereby, when the sealing plug is inserted in a suitable hole, with the sleeve (1) entirely within the hole, and increasing force is applied to the stem (2) with respect to the sleeve (1), axial compression is applied by the shoulder to the sleeve material abutting it, thereby causing the annular protrusion (9) on the stem head (4) to embed into the sleeve (1), and the sleeve to deform and expand radially to engage with the wall of the hole, and thereafter the stem (2) breaks at the weakened portion so that the head (4) remains in the sleeve (1).

摘要： A fastener installation tool for installing fasteners of the type in which a part of the fastener is broken off during installation. The tool is provided with a collection means (21) for collecting broken-off fastener parts during operation of the tool, the collection means being removably connectable to the tool. The tool includes retaining means (28) for retaining the collection means (21) against removal from the tool and the retaining means is air-pressure actuated into the retaining condition. The tool may include resiliently urged shutter means (38) which are held open when the collection means (21) is attached.
