This is a genuine lock nut replacement. This is a general piece of hardware that is often used on several types of lawn and garden equipment, including in engines, housing, and other areas. The exact application of this part will vary based on the unit. The lock nut is used to create a more secure seal than a standard nut. When properly secured, the lock nut tightens to a bolt and uses an extra locking washer with teeth to ensure a snug fit.If lock washers do get damaged or lost, they need to be replaced immediately with a genuine OEM replacement. This model is compatible with all types of machines and units since it is a generic part. The washer is sold as an individual part and manufactured by Whirlpool. Lock nuts will need to be installed using a socket wrench or adjustable wrench. Pliers, a screwdriver, or another socket wrench will be needed to hold the bolt while the lock nut is being secured in place. Be sure to thread the lock nut carefully to ensure a strong seal and avoid stripping the bolt or the nut.

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. This screw holds the gear in place and is exposed to constant vibrations and repetitive motion as a result. Over time, that can result in damage, wear, or even total breakage of the bolt and require a replacement. If the bolt isn't functional or is missing, the steering segment gear will not be secured and that can lead to further damage if left unattended. Using a genuine replacement part like this will guarantee an exact fit for compatible models. This genuine OEM gear bolt is manufactured by MTD. 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. The bolt works for more than 100 compatible models. It is made of durable metal and sold as an individual unit. A wrench or socket will be required to replace this part. Always wear gloves when performing repairs on lawn and garden equipment and allow the engine to cool before doing any work.

There are multiple uses for the 5/16-18 Hex Screw. It is often used with small gasoline-powered yard equipment such as lawn and garden machines. While hex screws such as these may be used in edgers and snowblowers, the most frequent use this screw is in yard tractors. This variety of screw is commonly used in attaching the various appendages of gas-powered equipment to a central operating platform. In particular, these hex screws are used to secure the engine block of power tools to the frame or housing of the equipment. Once in place, these fasteners have an almost unbreakable strength to them. This is so much so the case that often, in order to detach the engine manifold and repair the inner workings of an engine, the bolts must be chiseled or cut loose. In such cases, it is necessary for the bolts to be replaced during reassembly. Manufacturers insist that genuine OEM replacement parts be used in the rebuilding process. These replacement parts were manufactured to the same exacting specifications used to make the original screws. These OEM screws are compatible with equipment made and sold by Yard-Man, Cub Cadet, Troy-Bilt, Husky, MTD, Bolens, and Yard Machines.
