The Ultimate Guide to Self-Drilling Hex Head Screws (Hex Tek Screws)

When it comes to efficiency, durability, and performance on the jobsite, one product consistently tops the list for pros in the field: Self-Drilling Hex Head Screws, commonly known as Hex Tek Screws. At American Fasteners, these are among our best-selling items — and for good reason.

Hex Tek screws are self-drilling fasteners designed to cut through metal or wood without the need for pre-drilling. That means faster installation, less tool wear, and cleaner finishes. Whether you’re working with steel framing, metal roofing, or aluminum paneling, Hex Tek screws get the job done with precision and speed.

Contractors love them for their built-in drill point, which saves time on every job, and their hex head drive, which provides better torque and less slippage compared to Phillips or flat heads. They’re available in multiple finishes — including bronze, white, zinc-plated, and stainless steel — to match your project’s requirements. Plus, they’re cost-efficient, helping reduce labor time without sacrificing strength.

You’ll find Hex Tek screws being used in a wide range of applications, including fence and gate installations, HVAC ductwork, electrical and data tray mounting, as well as metal studs, roofing, and siding projects.
