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.

Flat washer for lawn mowers and outdoor power equipment. Replace if washer is missing, damaged, or corroded to ensure proper fastening and fit.

This washer is compatible with most lawn mowers and lawn tractors. The smooth, round edges fit perfectly with 5/8-inch bolts to attach the bolts to parts on the mower, as necessary. The washer provides a buffer between the bolt and the surface that it is being attached to. They are highly recommended for protecting parts that are being fastened together.The lack of a washer can cause permanent damage to the piece that the bolt is attached to. If the bolt does not have a washer to prevent it from moving and rusting, it can cause the bolt to fail. With products such as lawn mowers, this can spell disaster for both the appliance and its handler. These washers are high-quality and will prevent excess corrosion for the bolt. However, moisture and residue left after use can cause the washers to fail. In this case, a replacement will be necessary. This replacement part is compatible with most lawn mowers and tractors. This includes Ace, Ryobi, and MTD. This is an OEM replacement part sourced directly from the manufacturer. Sold individually.
