Flare nut wrenches are specially designed for the multi-sided nuts often seen on plumbing tubes and automotive brake lines. These tools typically have four or more contact points and an open end to nearly surround the nut. Similar to a crescent wrench, it has more facets to reduce stripping and increase torque. This is especially helpful for old or rusty flare nuts made of soft metals. Whether they're Craftsman, GearWrench, Armstrong or other quality brands, Sears has flare nut wrenches in many sizes at affordable prices.
Flare nut wrenches usually have two open ends with two different sizes. While flare nuts are their most common use, Craftsman standard and metric flare nut wrenches are also effective on hexagonal nuts made from copper, brass or aluminum. Most brands are made of steel with a polished or flat finish.
Measure the nut diameter carefully for a snug hold or gently place the tool on top to test for the proper fit before using. Metric and standard sizes are not interchangeable, and can cause rounding of the contact points when the wrong size wrench is used. Repeatedly forcing an improper fit over time can also damage the sturdiest quality tools. Buy a single wrench with the right size or buy a flare nut wrench set with several sizes at a reasonable price.
Sears carries a wide selection of both standard and metric wrench sets and from different brands to suit your needs. For example, GearWrench offers both regular and flex-head styles. Flex heads bend at a joint to allow access to nuts at odd angles or small spaces. Some styles offer the same size on both ends, with one open and the other enclosed for extra torque when needed.
Use a single flare nut wrench to complete a project or keep several sizes on hand for various automotive and household fittings. Shop at Sears today for all of the flare nut wrenches you need.
