Abstract
A tool for placing fasteners of the kind having a threaded first part which is pulled towards and/or into a second part to place the fastener without the need to accurately align the tool with the fastener, comprises a tubular nosepiece providing an annular abutment face for abutting the second part of the fastener and a mandrel which extends through the nosepiece and has a threaded part which projects forwardly of the abutment face for threadedly engaging the first part of the fastener. A draw bar which is rotatable and reciprocable on the tool axis which extends through the annular abutment face at right angles thereto transmits rotary and reciprocating motion to the mandrel through a universal joint whereby the mandrel is given freedom to move pivotally out of alignment with the tool axis. A tube surrounds part of the mandrel and limits the freedom of movement of the mandrel, and is movable along the tool axis. In one embodiment the tube is reciprocated and rotated with the mandrel and in another embodiment, the tube is not obliged to rotate or reciprocate with the mandrel. The tube projects forwardly of the abutment face when at the forward end of its reciprocation and engages the fastener and assists correction of alignment of the tool and prevents inward collapse of the fastener.
