Features: SUPERCOMBO® open end has specially designed grooves that direct wrench force away from fastener corners SUPERTORQUE® box opening design allows application of higher torque without rounding or deforming hex fastener points
Box and open end openings are identical Black Industrial Finish with SUPERTORQUE reg Box End and standard open end.
Instead, wrenching forces are placed on the flat surfaces behind the points
May be used on all common hex 6 point fasteners with considerable advantage over conventional box end wrenches to increase both hand tool flexibility and economy
Meets or exceeds aerospace specification AS 954 for 12 point fasteners as defined by AS 870 to provide accurate torque/tension relationship for precision application
No contact is made at the corners
