This is a genuine replacement bolt that is designed specifically for use on select lawn tractors. This tractor bolt is a specialty piece of hardware designed for use on the steering segment gear.

It is compatible with lawn and garden equipment from RYOBI, HUSKEE, Troy-Bilt, Bolens, Yard Machines, Yard Man, and Cub Cadet, along with select models from MTD.

Fix loose or vibrating parts with this jam nut. Used as a locknut to secure standard nuts in place on mowers and tractors. Easy 5-minute installation.

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.

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.
