The jam nut can be used in different locations within various types of lawn and garden machines. It is often used as a type of locknut that is jammed against a standard nut. This will help to lock both of the nuts in place. The jam nut is also considered a low profile nut, as they are usually half as tall as a regular nut. Owners may find that they eventually need to replace the jam nuts that came with their equipment. The replacement might be needed because one of the nuts is no longer holding tightly, or because it has been worn down or corroded. Additionally, the owner may have lost a nut when working on other parts of the machine. Replacement is fast and simple. Many buyers choose to get several of the nuts at once to have some on hand when needed. The genuine OEM jam nut is identical to those that came with the machine. It is sold individually and works for equipment such as lawn mowers, lawn tractors, tillers, and log splitters. Compatible brands include Craftsman, Toro, Cub Cadet, Ryobi, Troy-Bilt, Murray, Yard Machines, MTD, Huskee, Montgomery Wards, Bolens, Yard-Man, and MasterCut.
