Metric Steel Phillips Rounded
Head Drilling Screws for Metal
Drill a pilot hole, cut threads, and fasten in one motion with these metric-threaded screws. They're self-drilling, meaning they have a pointed tip that forms a pilot hole as they enter your material. As they turn, they also cut their own reusable threads, so you don’t need to drill and tap a hole first. Designed for fastening metal to metal, these screws are often used to install ducts and other assemblies where you can only access one side. The rounded head gives your project a finished look. Made of steel, they’re strong and wear resistant. They’re also plated with zinc to protect the steel from rust and extend the life of the screws. They meet ISO and DIN dimensional standards.
The miminum thread length may vary for screws with an overall length of 50mm or longer.

Stainless Steel Flat Head Drilling Screws for Metal
Standard Flat Head
Made from stainless steel, these screws are more corrosion resistant than steel, and almost as strong. All are beveled under the head for use in countersunk holes. They save you time and effort by drilling their own holes and fastening in a single operation. Length is measured from the top of the head.
18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. Use them to drill through aluminum and sheet metal.

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.

Flat Head Drilling Screws for Aluminum
Beveled under the head for use in countersunk holes. Use these screws to fasten aluminum to aluminum and steel framing. They save you time and effort by drilling their own holes and fastening in a single operation. Made from alloy steel, they're coated to resist corrosion in wet environments. Length is measured from the top of the head.

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.

Strip-Resistant Drilling Screws for
Joining Drywall to Metal Framing
Ribs under the head act as a brake to prevent over-tightening and damaging threads. A drill point powers through drywall and into metal studs up to 0.105" thick. These screws are made from steel and have a zinc-aluminum coating that resists up to 500 hours of salt spray. Length is measured from the top of the head.
