This is a flange nut that can be used in a variety of lawn and garden equipment from different manufacturers. The nut is made of metal, measures 5/16x18, and is used to secure components in place. It also assists with preventing backing out caused by vibration. Over time, the flange nut can become damaged and will need to be replaced. If the flange nut in lawn and garden equipment has become damaged, is loose, or gets lost, then replacement is required. The level of difficulty of replacing a flange nut depends on which parts it's securing and what kind of equipment it is installed on. This flange nut is an OEM replacement part that can be used with lawn mowers, snowblowers, wood chippers, tillers, log splitters, leaf blowers, and edgers by MasterCut, Craftsman, Yard-Man, Toro, Bolens, Cub Cadet, Montgomery Wards, Ryobi, Huskee, Troy-Bilt, MTD, and Yard Machines.

This flat washer is used to attach the idler pulley in a number of small and medium sized gasoline powered engines. These engines include snow blowers, log splitters, riding mowers, lawn tractors, and chippers. Because the idler pulley is subject to a great deal of resistance when the pulley is engaged, eventually the pulley will wear out. Should there be a squealing sound when engaging the drive, the problem is likely the idler pulley. In these cases, the pulley must be replaced. It is a good idea to replace the surrounding hardware when replacing the idler pulley; tNhis includes the flat washer, which is subject to corrosion during heavy use. To replace the idler pulley, first detach the spark plug cap. If on a mower or tractor, drop the mower deck. Remove the original pulley and install in order: replacement pulley, hex bolt, flat washer, flange nut. Apart from dropping the mower deck, the only tools required to complete this installation may be a 9/16 ratchet and combination wrench.
