Once everything is secure, drill a pilot hole using a bit with a slightly smaller diameter than the lag screw that will be used. When drilling the hole, make sure to drill all the way through the area where the screw will eventually be. Lag screws are also only available with hex heads while more common wood and sheet metal screws are available in multiple head types. With the sole option of a hex head, installation of the screw will require a nut driver or ratchet. A right driver bit and a power drill can be used to finish the tightening of the lag screw. The hex head lag screw is designed that way since hex headed fasteners are made to hold up in applications where a lot of torque is necessary. Lag screws have sharp lead thread points and are available in Steel/Zinc, Stainless Steel, and Steel/Hot Dip Galvanized.
