The difference is in the points. A TorquePlus socket features rounded points which allow the socket walls to contact the fastener walls, keeping pressure off the points. This engineering change helps the socket find a longer, better grip on the flat of the fastener head. All Sidchrome hand sockets feature the innovative TorquePlus design.
