HR-05Drill your pilot holesEven outdoors, take a second to think about what's behind the timber. If your shed has power run to it for lighting or a socket, cables are sometimes clipped to the inside face of the frame exactly where you're about to drill, so check the run visually inside before you drill all the way through. Drill a pilot hole roughly 2mm narrower than your screw's thread, to a depth just short of the screw length, so the screw's own thread cuts a tight grip rather than the hole doing the work.
