21 x 24 mm 12-Point Metric Double Head 10° Offset Box End Wrench - J.H. Williams

SuperTorque™ box opening design allows application of higher torque without rounding or deforming hex fastener points. No contact is made at the corners. Instead, wrenching forces are placed on the flat surfaces behind the points. 10° offset box end allows clearance in tight areas. Sizes are clearly marked on handle ends
