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 tool system is provided and includes a securing element, a hammer element configured to drive a member toward the securing element and first and second orientation elements rigidly disposed on the securing and hammer elements, respectively. The securing and hammer elements have respective operational axes and the first and second orientation elements respectively include orientation sensors configured to cooperatively determine a relative orientation of the respective operational axes.

A blind riveting device is provided, which is adapted for engagement to a handle having a powered translating member projecting therefrom. Force from the translating member imparted to a drive piston moves a second piston to pull a blind rivet connected to a jaw engaged with the second piston, thereby mounting the blind rivet.

A tool for installing a blind fastener including a core bolt and a core nut is provided. The tool includes a driving member, a collet driven by the driving member for engaging the core bolt, and an external sleeve for holding the core nut and preventing the core nut from rotating during installation of the blind fastener. The external sleeve is movable between a first position in which the external sleeve is driven by the collet to rotate with the collet and a second position in which the external sleeve is stationary despite rotating action of the collet.

A pneumatic riveter may include a jaw assembly (110) configured to extend around a portion of an object through which a fastener is to be driven, a lever (222) configured to be actuated to initiate rivet driving, a valve assembly portion (230) comprising a piston configured to enable progressive control of rivet driving responsive to actuation of the lever, and an unlocking assembly. The unlocking assembly may be configured to selectively inhibit operation of the lever responsive to positioning of a button (240) of the unlocking assembly in a locked position, and enable operation of the lever responsive to positioning of the button in an unlocked position.

A fixing gun includes a gun body and a loading device. The gun body is for manipulation of a fastener, and has a loading hole. The loading device includes a guide member and a linkage mechanism. The guide member is formed with a first guide groove and a second guide groove. The linkage mechanism includes a lower link, a slide member, and a clamp assembly for holding the fastener. The slide member is disposed movably on the guide member. The lower link is pivoted to the slide member and the clamp assembly. During movement of the slide member relative to the guide member for moving the fastener into the loading hole, the lower link is alternatively engaged to the first guide groove and the second guide groove.
