Bulk Loose Self-Drilling Screws

Self-Drilling Screws for Fastening Metal to Metal

Built for speed and precision, these self-drilling screws are designed to fasten metal to metal without the need for pre-drilling. With fine threads, hardened tips, and corrosion-resistant finishes, they deliver strong, lasting holds in structural steel, light-gauge framing, and more, all while increasing your efficiency on the job.
Self-Drilling Screws with Seemingly Unlimited Options

Our self-drilling screws come in a wide range of options to tackle everything from metal-to-metal and wood-to-metal fastening to interior framing and exterior cladding. Choose from multiple head styles, drive types, and corrosion-resistant finishes like zinc, galvanized, ceramic-coated, and stainless steel, each built for strength, speed, and long-term performance.
The Right Point for Every Project

Different point types pierce various materials. Standard points handle light- to medium-gauge metal, long points tackle thicker steel, self-piercing points work well in wood or thin metal and winged points clear softer layers before drilling harder substrates, ensuring faster, cleaner and secure installations.
