Hex lock nut secures bolted joints on outdoor lawn equipment. Replace if threads are stripped, nut is missing, or won't hold proper tension.

The lock nut is a piece of standard hardware that may have a variety of applications on lawn and garden equipment, including on engines, housings, and other components. The lock nut offers a secure fit by tightening into a flange that prevents the nut from loosening like a regular nut might. Over time, the flange or the nut can become worn or damaged. In some cases, lock nuts may be lost during the process of other repairs or maintenance. Replacing them with genuine OEM parts like this lock nut is the best solution. This lock nut is compatible with hundreds of machines, including mowers, snowblowers, and chippers from MTD, Troy-Bilt, Cub Cadet, RYOBI, Yard-Man, Yard Machines, Bolens, and Husky. The ¼-inch lock nut has multiple locations and applications, so owners should consult their parts diagram for exact placement and part number identification. This lock nut is made of durable metal and sold as a single unit. Those who need additional pieces will have to order multiple quantities. This part will require a wrench or a socket to replace, as well as pliers and/or a screwdriver to hold the bolt or screw in place.
