There are multiple uses for the 5/16-18 Hex Screw. It is often used with small gasoline-powered yard equipment such as lawn and garden machines. While hex screws such as these may be used in edgers and snowblowers, the most frequent use this screw is in yard tractors. 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.
