This hex screw and lock washer are commonly used with lawn mowers and other small engines to secure a motor to the housing of the equipment. It is machined in such a way that it binds the manifold and frame permanently. There are occasions when these bolts have to be removed, typically when major repairs are performed on the engine. In those cases, users often find it advisable to replace the hex bolts and washers with new ones. It happens as well that these screws are so tightly fastened that they cannot be unscrewed and must be cut off. In those cases, it is necessary to replace the original screws. These replacement screws and lock washers are genuine OEM certified replacements that are manufactured to be identical to the hardware they are replacing. In addition to mowers, these hex screws are used to secure engines to devices such as log splitters, edgers, shredders, trimmers, and snowblowers. This screw is compatible with devices made by Husky, Yard-Man, Cub Cadet, Troy-Bilt, Ryobi, Bolens, and Yard Machines.

This is a flanged lock nut. It’s designed to apply tension, typically on a joint that needs to have a certain amount of flex. As such, it’s mostly used on snowblower chutes and lawnmower handles. They can remain in place, but with a forgiving connection that can take a beating. The nut size is 3/8, with a thread size of 16. A lock nut will generally last for many years. However, the silicone ring inside will wear down if it’s frequently tightened and loosened. It needs to be replaced when it will no longer reliably remain in place. Generally, this begins as a symptom of slight slippage and worsens as time goes on. Thankfully, whether it’s being used on a snowblower or a lawnmower, this nut is generally straightforward to access. Simply unscrew the old nut, then screw the new nut on until it’s nice and tight. Our flanged lock nuts are genuine OEM MTD nuts, and they are sold individually.
