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 air cleaner cover is designed to house the air filter on larger lawn equipment and other outdoor power tools. There is no aspect of small engine care more necessary than protecting the air that goes into the carburetor and cylinder from yard dust. Nothing is more incapacitating to a small engine than being clogged with dust, pollen, and other particulates that are invariably stirred up during landscaping work. While the air cleaner cover itself is not a moving part and would not seem to be subject to replacement, it is occasionally the case that, through extensive use or accidental contact, the cover becomes unable to shield the air filter within it. In these cases, it is essential to replace the cover with an OEM certified replacement cover that has been manufactured to the same specification as the original. Though replacing the cover itself is quite simple, it probably a very good idea to replace the air filters at the same time. If the cover is in need of replacement, it is quite likely the filters have been exposed to excessive amounts of particulate. This cover can be used on chippers, shredders, log splitter, mowers, and a variety of other small engine/large job equipment. Compatible brands include Troy-Bilt, MTD, Yard-Man, Yard Machines, and Cub Cadet.
