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.
