Stainless Steel Flanged Hex Head Screws for Wood
These 316 stainless steel screws have excellent resistance to chemicals and salt water and are a good choice for ACQ-treated (arsenic-free) lumber. The flange reduces the risk of crushing material and the hex head provides a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Screws may be mildly magnetic. Head height includes the flange. Length is measured from under the head.

Steel Flanged Hex Head Screws for Wood
These steel screws are hot-dipped galvanized to resist corrosion in wet environments and are a good choice for ACQ-treated (arsenic-free) lumber. The flange reduces the risk of crushing material and the hex head provides a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Head height includes the flange. Length is measured from under the head.
