Lost or broken push cap preventing setting adjustments? This small but essential control cap restores proper function on mowers and tractors. Quick fix.

This genuine OEM replacement jam nut attaches to the idler bracket on a tiller. Jam nuts are a special type of nut designed to not unthread or strip out over time. Jam nuts are usually fastened on with another standard nut and then the two nuts are tightened against each other. Jam nuts can be easily identified from a standard nut because they are roughly half the size. Jam nuts can be lost while making repairs because of their small size. If lost, it might not affect the idler bracket immediately, but over time the standard nut may begin to slip or unthread. Therefore, the jam nut should be replaced as soon as possible. When making this replacement, be sure to unthread the standard nut as well and then tighten them both together using a wrench. This replacement jam nut is a high-quality part sourced from its original manufacturer. It is compatible with Troy-Bilt, Yard Man, Huskee, MTD, Ryobi, Yard Machines, and Cub Cadet tillers. This part does not ship with any additional hardware.

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.

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. If it appears to be broken or weak, a replacement is required. Flange locks can be adjusted and uninstalled after use. 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 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.
