Hex bolt fastener for lawn mowers and outdoor power equipment. Replace this bolt if cracked, stripped, or missing to secure engine and frame components.

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. This bolt is compatible with the following brands: Yard-Man, Bolens, Craftsman, Yard Machines, Troy-Bilt, Cub Cadet, Huskee, Ryobi, Murray, MTD, MasterCut, and Montgomery Wards.
