Screw for lawn mowers, snowblowers, tillers, and outdoor power equipment. Replaces broken, stripped, or missing screws in internal or external machinery.

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.
