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 bolt is a necessary component used in a variety of small to medium sized gasoline powered engines used primarily in yard work, gardening, and landscaping. The primary use of this hex bolt is to secure the idler pulley assembly to the body of the machine. The idler pulley functions to engage the turning mechanism of the yard tool when engaged. The power yard tools that require an idler pulley which would use this screw are tillers, riding mowers, yard tractors, tillers, snow blowers and chippers. Engaging the rotating part of the yard tool places a great deal of resistance on the idler pulley, which may eventually result in it needing to be replaced. When replacing the idler pulley assembly, it's important to remember that the attaching hardware, such as the hex bolt, has also experienced a great deal of wear and should be replaced as well. This hex bolt attaches the idler pulley assembly directly to the machine housing and can be removed with a 9/16 wrench.

With small gasoline-powered tools that require control panels, this hex screw attaches the panel to the handles of the tools. Machined to be durable, important screws such as these take a real beating. In their locations at critical points on the handle, the hex screws are considered "wear items," and thus periodically, they must be replaced. The control panel itself is often a location of extreme forces, jostling, and abrupt movement in unpredictable directions. The constant movement, with sheet metal rubbing against the hex screws from every direction, make wear inevitable. The manufacturers recommend that spare screws of this type be kept on hand if the heavy use of the equipment is expected. Among the gasoline-powered tools that use these screws are snowblowers, yard tractors, mowers, tiller, chippers, shredders, and other tools requiring hand-maneuvered levers. These screws are compatible with a number of equipment brands and manufacturers, including MTD, Ryobi, Poulan, Yard-Man, Bolens, Troy-Bilt, and Yard Machines.
