18-8 Stainless Steel Hex Head Drilling
Screws with Hardened Steel Tip for Metal
These 18-8 stainless steel screws have a hardened steel drill point to penetrate steel and are coated to increase corrosion resistance. All have a hex head for a secure grip with a wrench and a flange to reduce the risk of crushing thin metal. They save you time and effort by drilling their own holes and fastening in a single operation. Length is measured from under the flange. Head height includes the flange.

Stainless Steel Hex Head Drilling Screws for Aluminum
Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Use them to fasten aluminum to aluminum and steel framing. The hex head allows for a secure grip with a wrench and a flange reduces the risk of crushing thin metal. They save you time and effort by drilling their own holes and fastening in a single operation. Length is measured from under the flange. Head height includes the flange.

Stainless Steel Phillips Drilling Screws for Joining Wood to Metal
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. They speed installation by drilling, tapping, and fastening wood and metal in a single operation. Length is measured from the top of the head.
Screws with cutting wings drill a slightly larger hole in the wood to allow for expansion. The wings break off when they contact metal, so the screw can tap the remainder of the hole.
