A mechanical part includes a part body provided with a through-opening, and a through-fastening element including a rod engaged in the through-opening and connected to an inner surface of the through-opening by a support fastened to the rod of the through-fastening element and to the inner surface of the through-opening and configured to break the link between the rod of the through-fastening element and the inner surface of the through-opening, under the effect of a thrust applied on the through-fastening element so as to push the rod of the latter into the through-opening. Due to the fact that the through-fastening element is pre-integrated with the mechanical part, the logistical management prior to assembly of the mechanical part to another mechanical part is simplified, the risk of operator errors and loss of the fastening element are reduced.

An assembly system with a sealant application station and an assembly tool is described. The assembly system is used to connect two or more components to each other. The sealant application station applies a sealant to a connector. The sealant application station is arranged in a feed system for the connectors. The sealant-applied connectors are transferred to the assembly tool. The assembly tool contains a drill spindle in which a connector and a drill can be axially aligned with each other so that the drill spindle can both drill a hole in the components to be connected and position the connector in the drilled hole with a linear movement along a processing axis. For these operations, the drill spindle moves only along the processing axis, so that a linear drive can be used for these operations.

A collet assembly including an actuator and a collet connected to the actuator. The collet assembly is adapted to be installed on a welding electrode holder having an electrode. The collet is moveable by the actuator from an advanced position, in which the collet is adapted to grip a fastener such as a welding rivet, and a retracted position, in which at least a portion of the collet is retracted into the actuator to enable the electrode to engage the fastener for welding to a work piece, and the collet is adapted to release the fastener.

A blind rivet setting tool including a channel along which the broken mandrels of set rivets can be moved and biasing means for biasing blocking means into the channel for blocking the movement of a broken mandrel along the channel whereby a broken mandrel must urge the blocking means out of the way against said bias in order to move past the blocking means.

A blind rivet setting tool including clamping means for releasably clamping a nosepiece in place such that a blind rivet can bear against the nosepiece while the mandrel thereof is pulled; and a method of changing nosepieces using the clamping means.
