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 hex bolt is a necessary component used in a variety of small to medium sized gasoline powered engines used primarily in yard work, gardening, and landscaping. The primary use of this hex bolt is to secure the idler pulley assembly to the body of the machine. The idler pulley functions to engage the turning mechanism of the yard tool when engaged. The power yard tools that require an idler pulley which would use this screw are tillers, riding mowers, yard tractors, tillers, snow blowers and chippers. Engaging the rotating part of the yard tool places a great deal of resistance on the idler pulley, which may eventually result in it needing to be replaced. When replacing the idler pulley assembly, it's important to remember that the attaching hardware, such as the hex bolt, has also experienced a great deal of wear and should be replaced as well. This hex bolt attaches the idler pulley assembly directly to the machine housing and can be removed with a 9/16 wrench. Make sure when replacing the bolt to use a genuine OEM manufactured part that is identical to the manufacturer's original piece.

A flange lock nut, also known as a flange lock or a lock nut, is created to be used in various types of lawn and garden equipment. This flange lock nut holds other parts in place and, when properly threaded, will resist loosening. Over time, a flange lock nut may begin to weaken and may become loose or break.

When replacement is required, you may need a socket set, screwdriver, hacksaw, and butane torch. The socket wrench will loosen the bolt it is connected to, while the torch is used to heat the lock nut. A socket wrench may remove the nut, but sometimes cutting it with a hacksaw is required. This flange lock nut is a genuine OEM component directly from the manufacturer and comes in an individual unit. It is made of metal, a gold color, and can be found in various areas of lawn equipment.

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.
