This lock washer is used frequently for a number of applications on power yard equipment. The size, 5/16, is the default for many small engine housing and manifold applications. Lock washers are used with machined bolts to fasten engine blocks to the housing of the equipment being used. The compressed washer is able to handle the constant vibration of the small gasoline engine without losing the seal between the screw or bolt and the housing. Typically these lock washers only need to be replaced when they are misplaced during repairs or when the screws that attach them have to be chiseled or cut away, meaning the washers are destroyed as well. These OEM certified replacement washers have been manufactured to the same specifications as the originals they are replacing. In addition to lawn mowers, lock washers of this type and size are frequently used on blowers, lawn tractors, cultivators, snowblowers, and trimmers. Brands compatible with this type of washer are Murray, Husky, Poulan, Bolens, Yard-Man, Cub Cadet, Troy-Bilt, Yard Machines, MTD, and Ryobi.

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.
