Note: If the area of the hex drive is smaller
than the square drive, HYTORC will dis-
claim any liability for broken hex drives or
hex sockets. These male hex sockets are
excluded from warranty claims:
• 1/2” x 17 mm (11/16") and smaller
• 3/4” x 22 mm (7/8”) and smaller
• 1” x 27 mm (1 1/8") and smaller
• 1 1/2” x 46 mm (1 5/6”) and smaller
• 2 1/2” x 70 mm (2 1/2”) and smaller
Extra shear forces and bending forces
caused by an imperfect reaction level
and/or a short reaction distance will lower
the specified torque values in the table.
• Male hex socket
