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. 14 AF SocketsStandard: 15/16, 1”, 1-1/16, 1-1/8, 1-3/16, 1-1/4, 1-5/16, 1-7/16, 1-1/2,1-11/16, 1-3/4, 1-13/16, 1-7/8, 2”Ratchet, Reversible Male500mmExtension200mmExtension400mmAdjustable Offset Handle500mmUniversal Joint

• Sidchrome TORQUEPLUS sockets are particularly useful on worn or rounded fasteners.
