Williams 1214RSC Red Super Combo Combination Wrench 7 16-Inch

From the Manufacturer Snap-on Industrial Brand JH Williams 7/16-Inch red super combo combination wrench is a standard wrench with a high visibility red finish and 12 point box end. The wrench has a red super combo open end as well as a super torque box end. The open end has specially designed grooves that direct wrench force away from fastener corners. The super torque 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. It 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. The box and open end openings are identical.
