This replacement part is a hex screw, and it is intended for use in different types of lawn equipment. This is a genuine replacement part made by MTD. This screw can be used in a variety of ways depending on the repair needed. Hex screws are similar to normal screws except they have a six-sided head, like a hexagon. A new hex screw might be needed if the current one is damaged or missing. It is common that screws may become stripped or loose overtime, causing them to fall out. If any parts of the lawn mower are becoming loose or falling off, the hex screw might be missing. This replacement should be fairly easy and should only require a screwdriver and possibly pliers.

With small gasoline-powered tools that require control panels, this hex screw attaches the panel to the handles of the tools. Machined to be durable, important screws such as these take a real beating. In their locations at critical points on the handle, the hex screws are considered "wear items," and thus periodically, they must be replaced. The control panel itself is often a location of extreme forces, jostling, and abrupt movement in unpredictable directions. The constant movement, with sheet metal rubbing against the hex screws from every direction, make wear inevitable. The manufacturers recommend that spare screws of this type be kept on hand if the heavy use of the equipment is expected. Among the gasoline-powered tools that use these screws are snowblowers, yard tractors, mowers, tiller, chippers, shredders, and other tools requiring hand-maneuvered levers. These screws are compatible with a number of equipment brands and manufacturers, including MTD, Ryobi, Poulan, Yard-Man, Bolens, Troy-Bilt, and Yard Machines.

This variety of screw is commonly used in attaching the various appendages of gas-powered equipment to a central operating platform. In particular, these hex screws are used to secure the engine block of power tools to the frame or housing of the equipment. Once in place, these fasteners have an almost unbreakable strength to them. This is so much so the case that often, in order to detach the engine manifold and repair the inner workings of an engine, the bolts must be chiseled or cut loose. In such cases, it is necessary for the bolts to be replaced during reassembly. Manufacturers insist that genuine OEM replacement parts be used in the rebuilding process. These replacement parts were manufactured to the same exacting specifications used to make the original screws. These OEM screws are compatible with equipment made and sold by Yard-Man, Cub Cadet, Troy-Bilt, Husky, MTD, 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.
