This hex screw and lock washer are commonly used with lawn mowers and other small engines to secure a motor to the housing of the equipment. It is machined in such a way that it binds the manifold and frame permanently. There are occasions when these bolts have to be removed, typically when major repairs are performed on the engine. In those cases, users often find it advisable to replace the hex bolts and washers with new ones. It happens as well that these screws are so tightly fastened that they cannot be unscrewed and must be cut off. In those cases, it is necessary to replace the original screws. These replacement screws and lock washers are genuine OEM certified replacements that are manufactured to be identical to the hardware they are replacing. In addition to mowers, these hex screws are used to secure engines to devices such as log splitters, edgers, shredders, trimmers, and snowblowers.
