Tapping Method
Steel Hex Head Wood Screws
 |
Often used on posts and beams, the coarse threads on these screws dig in for a firm hold. The hex head's six contact points keep sockets in place to avoid slipping and stripping the drive. To tighten, use a wrench or six-point hex socket. Also known as lag bolts.
Drill a pilot hole slightly smaller than the screw to prevent splitting. Length is measured from under the head.
Black-Zinc-Plated Steel—The dark zinc plating withstands occasional exposure to moisture while creating a finished look.
