A nutsetter is a tool used to provide fast and easy screw and nut installation or removal. These tools provide a reliable grip on metal screws and other hex head fasteners and, when combined with a drill or power tool, they can quickly tighten or loosen them.
Lobular Design- drives in the fasteners by focusing on the sides instead of pressuring the corners to install. A lobular nutsetter allows a gap at the corners in case of paint build up and it will keep the fasteners in good shape.
Hex Design- this standard form uses the corners to drive in a fastener. Too much pressure on the fastener can cause corner stripping.
