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.

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.

Secures wheels and attachments to axles on lawn mowers and tractors. Replace if bent, rusted, broken, or lost to restore safe equipment operation.

Cotter pins are simple but very effective fasteners used primarily to hold wheels in place on mowers. This is particularly true of the front wheels on riding mowers. Cotter pins are very light and can become overly pliable after extensive use. In some cases, the front wheels of a mower, which are the guide wheels that steer the device, become difficult to manage. The cure for this situation is often simply the replacement of the cotter pins that are not holding the guide wheels adequately in place. Before attempting to remove the pins, it is essential that the spark plug boot is moved so that the mower cannot be started. This is an important safety step because the repairer will be getting under the mower near the blades. The back wheels should be blocked so the mower cannot move, then the front end placed up on blocks. Remove the mower's hubcaps to gain access to the axle spindles. Straighten the legs of the pin so that when the curved portion of the cotter pin is grasped with pliers and it can be pulled straight back and be removed. The spindle, washers, and wheels should be checked for wear before the new pin is placed and secured. This OEM cotter pin is compatible with Bolens, Yard-Man, Craftsman, Yard Machines, Cub Cadet, Turf King, Troy-Bilt, Huskee, Toro, Ryobi, MTD, MasterCut, Murray, and Montgomery Wards.

The compressed washer is able to handle the constant vibration of the small gasoline engine without losing the seal between the screw or bolt and the housing. Typically these lock washers only need to be replaced when they are misplaced during repairs or when the screws that attach them have to be chiseled or cut away, meaning the washers are destroyed as well. These OEM certified replacement washers have been manufactured to the same specifications as the originals they are replacing. In addition to lawn mowers, lock washers of this type and size are frequently used on blowers, lawn tractors, cultivators, snowblowers, and trimmers.

A ball bearing is a common type of rolling-element bearing. It will use balls to keep space between the bearing races and eliminate friction and contact between moving parts. Ball bearings used in lawn and garden equipment ensure that axial loads and radial loads are evenly supported and that there is only a limited amount of rotational friction on the component.
