Weber Kettle Grills are perhaps the most widely used charcoal cooking devices around. In addition to being relatively inexpensive, they are designed to be easy to assemble and weather resistant, and they require virtually no maintenance. One of the only problems that you will encounter with a Weber Kettle Grill, specifically the models with a three-leg assembly, is that over time the legs will loosen and begin to fall off. The best way to permanently solve this issue is by installing screws through each of the leg collars into the aluminum leg.

Move the assembled grill to a level open area, and ensure that the legs are inserted into the leg mounting collars as far as they will go.
Beginning with the front leg (the one without a wheel) locate the dimple on the leg mounting collar. It will be on the side of the collar facing directly outward.
Insert the hex screw into the drill and driver bit, and line up the tip of the screw so that it rests inside the dimple of the leg mounting collar.
While holding the drill perpendicular to the leg assembly, drive the hex screw through both the mounting collar and the leg until the washer head is tight against the collar.
Move to either of the two remaining wheeled rear legs and repeat Steps 2 through 4.
