Spanner wrenches are often used in plumbing to help repair leaky pipes or faucets, especially those that haven’t been touched in many years. There are 3 main types of spanner wrenches, each with a distinctly shaped hook. The most common type of adjustable spanner wrench is the C spanner. Its head looks like the letter C, and its jaws are designed to correspond to the same size nut. The obstruction spanner has jaws that are steeply angled to help you reach nuts in confined spaces. The ring spanner has a completely enclosed ring that fits precisely over a hexagon or square bolt. Make sure your spanner wrench is the correct size and is properly aligned around the nut before twisting. Otherwise, it could slip from the wrench and cause injury. Our inventory includes many types of wrenches like adjustable wrenches, ratcheting wrenches, combination wrenches and more!
