Hex screw fastener for securing lawn mower components. Replace if stripped, rusted, or missing to ensure proper assembly and equipment stability.

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 lock washer is used frequently for a number of applications on power yard equipment. The size, 5/16, is the default for many small engine housing and manifold applications. Lock washers are used with machined bolts to fasten engine blocks to the housing of the equipment being used. 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. Brands compatible with this type of washer are Murray, Husky, Poulan, Bolens, Yard-Man, Cub Cadet, Troy-Bilt, Yard Machines, MTD, and Ryobi.

This self-tapping screw is used to attach various parts to the engine housing of medium sized gasoline powered engines, in particular yard tools such as tillers, snow blowers, yard tractors, riding mowers, power vacuums, shredders, and chippers. It is used in over 150 different gasoline powered engines. Screws such as these are used particularly when a device is going to receive a great amount of vibration and stress while the engine is running and rotating tools are engaged. Such devices sustain a great deal of wear over time and the parts subject to replacement will eventually fail and need to be replaced. In such cases, it is wisest to replace the attaching hardware such as housing screws as well, because it is a self-tapping screw. Screws of this type are designed to forge a tight bond between the metal pieces they are securing together, but once loosened, they should ideally be replaced with new hardware. Make sure when replacing these screws to use genuine OEM parts like these screws. These replacement parts are manufactured to be identical to the original pieces. This hex screw is compatible with the following brands: MasterCut, Yard-Man, Yard Machine, Montgomery Wards, MTC, Murray, Bolens, Craftsman, Turf King, Troy Bilt, Cub Cadet, Huskee, Toro, and Ryobi.

This hex nut is designed for use with select trimmers and mowers. It is a standard hardware part that may have multiple applications depending on the type of unit and model. The nut is typically used to secure engine components or housing elements to provide safe use of the machine. These nuts are durable, but they are small and can become lost during other repairs. The constant exposure to vibrations and use can also cause them to strip or become damaged over time. Either way, a replacement with this genuine hex nut will resolve the issue and get equipment back in working order. This genuine OEM hex nut is manufactured to exact standards and sourced from the manufacturer. It can be used with trimmers and mowers from RYOBI, MTD, Bolens, Troy-Bilt, Yard Machines, Huskee, Yard Man, and Cub Cadet. Check the parts diagram for exact application and location of this nut and note that it may have multiple uses on select models. This hex nut is sold individually, and additional nuts will require the purchase of multiple pieces. In order to replace this nut, a hex socket wrench and driver will be required. Always wear gloves for safety.

The ignition switch is the part of lawn and garden equipment that features an ignition to turn on and off with a switch. These are common on lawn tractors, as well as some lawn mowers, wood chippers, tillers, and log splitters. While these switches tend to be robust, they may eventually wear out. Some might have a mechanical failure after being used for years. Others might have electrical issues. Regardless of the reason for the failure, they will need to be replaced to continue using the machine. This is a genuine OEM part that is sold individually. It is a complete kit, which will include not only the switch, but also a washer and nut to secure the switch into the housing, and two ignition keys. The ignition switch can work with lawn tractors from brands such as MTD, Ryobi, Troy-Bilt, Bolens, Yard Machines, and Craftsman.
