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.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Steel Phillips Rounded Head Drilling Screws

Drill and fasten metal in one step and create a finished look with these rounded head screws. The Phillips drive withstands less torque than a hex drive, so apply even, steady pressure when drilling.

Length is measured from under the head.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
