ABSTRACT:
A pliers-type tool for setting pull-type blind fasteners of a kind requiring the stem of the fastener to be severed after it has been pulled to set the fastener. A pair of blades mounted on pivotal holders arranged to be rocked by an actuating member of the tool after the stem has been pulled is provided. The actuating member is slideably mounted on the pull bar and a tooth of a latch engages both parts during an initial part of the setting stroke. When the fastener has been set the latch becomes disengaged from the pull bar while continuing to retract the actuating member. Such disengagement is controlled by a cam which is adjustable on the housing of the tool to vary the length of stroke of the pull bar in accordance with the thickness of workpiece in which the fastener is being set.
