Features Flare nut wrench sets with a flex head on each end can swivel up to 90° to access fasteners from multiple angles. The 6-pt. the design allows more contact with the fastener's sides than the 12-pt. style and prevents rounding the fastener's corners. These double-end wrenches come in metric and SAE (inch) sizes. They have a different size on each end so that each wrench can be used for two different size fasteners. Wrenches have an opening in the wrench head that allows a line or other obstruction to pass through it. These sets include both SAE (inch) and metric sizes.
