Wood to steel self drilling screws are engineered to securely fasten wood, plywood, OSB, and dimensional lumber directly to steel without the need for pre-drilling. Also known as wood to metal screws or wood to metal fastening screws, these fasteners feature a hardened drill point that cuts through steel while aggressive threads securely grip the wood. The result is a fast, reliable connection that saves time on commercial, industrial, agricultural, and residential construction projects. Here you will find self drilling screws to attach wood to light gauge steel as well as thick steel up to 3/8". Choose from zinc, an exterior finish or stainless steel finish. See below products for more info on drilling capacity and recommended lumber thickness.
Fast, Efficient Wood-to-Metal Fastening
Whether you're installing wood blocking, furring strips, roof decking, plywood sheathing, or treated lumber,
wood to steel fasteners simplify installation by drilling and fastening in a single operation. These self drilling wood to steel screws eliminate pilot holes in most applications, reducing labor while providing excellent pull-out strength and long-term holding power.
Available in multiple diameters, lengths, head styles, and protective finishes, our
drill point wood to steel screws are designed for fastening wood to both light-gauge steel and heavier structural steel when matched with the proper drill point.
Common Applications
Wood framing to structural steel
2x headers to steel beams
Trailer decking
Wood nailers and blocking
Roof and wall sheathing
Furring strips over steel framing
Agricultural and post-frame buildings
Commercial and industrial construction
Equipment platforms and maintenance projects
Features & Benefits
Drills and fastens in one easy step
No pilot holes required in most steel applications
Reduces installation time and labor costs
High-strength hardened steel construction
Excellent pull-out and holding performance
Available with corrosion-resistant coatings

How to Choose the Right Wood to Steel Screw
Choose a screw long enough to fully penetrate the steel while providing adequate thread engagement in the wood. Select the appropriate drill point based on the thickness of the steel being fastened. For pressure-treated lumber or outdoor applications, choose corrosion-resistant finishes or stainless steel options for maximum durability. Keep in mind that the tip of the screw has no threads as it is a drill point.

If you're fastening wood to steel framing, many contractors search for
TEK screws for wood to steel. While "TEK" is a well-known industry term, it is also a registered trademark. Our selection includes professional-grade self drilling screws for steel framing that deliver the same reliable performance across a wide variety of wood-to-metal applications.
Frequently Asked Questions About Wood to Steel Self Drilling Screws
Do wood to steel self drilling screws require a pilot hole?
No. Wood to steel self drilling screws are designed to drill through steel and fasten wood in a single operation, eliminating the need for a pilot hole in most applications.
What are the little wings or tabs for on these screws?
The tabs or wings are designed to clear the wood as the screw drill through and then when the wings hit the steel, the wings break off. This prevents the lumber from raising up or "jacking" during installation.
What is the difference between a wood to steel screw and a standard self drilling screw?
Wood to steel self drilling screws are very similar to other self drilling screws but they typically have the countersunk head to sink into the lumber.
What drill point should I choose?
Choose the drill point based on the thickness of the steel you're fastening into. Point #3 is commonly used for lighter steel, while Point #4 is recommended for thicker structural steel.
Can these screws be used with pressure-treated lumber?
Yes, but you should select screws with a corrosion-resistant exterior coating or stainless steel construction when fastening pressure-treated lumber or when installing outdoors.
What tools are recommended for installation?
A variable-speed impact driver or screw gun with the correct magnetic nut setter provides the best performance. Moderate speed and steady pressure help the drill point cut cleanly through steel.
How do I choose the correct screw length?
Select a screw that fully penetrates the steel while allowing enough thread engagement through the wood. Our specification table above lists the recommended wood thickness for each screw size.
Can wood to steel self drilling screws be removed and reused?
While they can usually be removed, reusing fasteners is generally not recommended for structural applications because removal may reduce holding performance.
