Hex screw fastener for lawn mower and lawn tractor small engines. Secures components together. Replace if lost, stripped, or corroded during maintenance.

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.
