About Flare Nut Wrenches

Also called tube and line wrenches, flare nut wrenches are commonly used in the automotive and plumbing industries for loosening or tightening tube and pipe fittings. They provide better access to hard-to-reach fasteners than a box wrench and are less likely to damage fasteners made from softer metals such as brass and copper than an open-end wrench. 6-point flare nut wrenches have points along the inside edge of the jaw and make contact with all but one of the sides of a hexagonal fastener for good grip when turning or holding the fastener.

These two-in-one tools have a head on both ends of the tool, allowing a wider range of jobs to be accomplished with one tool. Each head fits a fastener of a specific size, and the heads may be the same or different sizes.
