Serrated threads on these domed-head screws cut through wood fibers of plywood and oriented strand board (OSB) to minimize splitting. They have a combination drive, so you can use Phillips drivers to tighten them or square drivers if you need more torque.

Length is measured from under the head.

Serrations on the flange grip material for a tighter, more vibration-resistant hold than other drilling screws. The flange also spreads the load to prevent crushing thin metal. Turn the hex head with a nutdriver or socket to drill and fasten in one step.

Serrated threads on these rust-resistant screws cut through wood fibers of plywood and oriented strand board (OSB) to minimize splitting. When exposed to moisture and chemically treated wood, such as ACQ-treated (arsenic-free) lumber, these screws won't rust or corrode. All have a domed head, and the Phillips drive handles enough torque to drive into most kinds of wood without slipping.

Length is measured from under the head.

Two ways to install—use a Torx driver in the recess or grip the hex head with a nutdriver for more torque. These screws drill and fasten in one step. The serrated flange grips surfaces to resist mild vibration and spreads the load to prevent crushing thin metal.

Fasten plywood and oriented strand board your way with these rust-resistant screws. They have a combination drive, so you can use Phillips drivers to tighten them or square drivers if you need more torque. The flat head sits flush to prevent snags, while serrated threads cut through wood fibers to minimize splitting. Often used in exterior panels, they won't degrade from moisture or chemically treated wood.
