A sealing plug comprises the combination of a stem and sleeve, in which the stem is designed to have an external taper such that, on installation of the plug by a setting tool, sleeve material flows into a gap between the sleeve and taper to assist with locking the sleeve and stem together. Furthermore, the tool nose piece has a conical taper designed to cause sleeve material to flow, initially on installation, radially outward to effect locking of the plug into a blind hole into which it is being installed.

Sealing plug

A rivet for fastening workpiece members, the rivet including a body comprising a shank extending in a first, longitudinal direction and a head extending in a second, substantially transversal direction, a bore being defined through the shank and the head of the body; and, a stem comprising a main longitudinal portion arranged for insertion into said bore, and an enlarged portion arranged for radially expanding the shank when the enlarged portion is forced into said bore to fasten the workpiece members; the rivet being configured for insertion into respective apertures formed in the workpiece members; and the rivet being further configured such that when the workpiece members are fastened, the head of the body of the rivet is displaced relative to the shank to engage with the stem to lock the stem in place relative to the body and/or the workpiece members.

Rivets

A lockbolt for installation into apertured workpiece members, comprising a pin having a head and a tail end provided with locking grooves and a single pull groove (), wherein an installation tool having a collet with a corresponding shape to the pull groove is used to apply an increasing pulling force to the pin tail, thereby to push the collet towards the workpiece, and as the force applied by the hydraulic piston further increases, causing the collar () to be swaged into the lock grooves, and halting the force applied by the tool either at a predetermined maximum value or when the pin tail breaks at a breaker groove formed by the single pull groove.

A blind fastener comprising a body () and a stem (), wherein the fastener is installed in a workpiece by applying a pulling force to the bodycausing a bulb to form at a radially expandable section of the body, the stem of the fastener comprising two waisted regions () of reduced diameter, such that when the body of the fastener is crimped after assembly with the stem, the body is caused to form a barrel shape, whereby clearance between the body and stem is minimized.

Blind fastener

A sealing plug for sealing a hole in a wall, which sealing plug is insertable into the hole by access from only one side thereof, which sealing plug comprises:
