48N024 - Walter #8 x 1/2" Hex Head Self-Drilling Screw

Drill and Fasten in Seconds

When you are in the middle of a fabrication job, you don't have time to switch between a drill bit and a driver bit for every single connection. The Walter 48N024 Self-Drilling Screw is your solution for rapid metal fastening. Known in the trade as a "Tek" screw, this #8 x 1/2" fastener is built to bite into metal instantly, drilling its own pilot hole as you drive it. It’s the perfect accessory for any welder or fabricator working with sheet metal, ducting, or steel framing.

The hex washer head is a standout feature for shop use. Unlike Phillips or Robertson heads that can strip out under heavy torque, the hex head gives your driver a positive grip that won't slip. This means you can drive these screws home with an impact driver or drill with full confidence. The integrated washer face provides a larger bearing surface, ensuring the screw holds the material flat and secure without pulling through thin gauge metals.

Walter Surface Technologies is known for quality, and their fasteners are no exception. These screws are made from hardened steel to prevent the heads from snapping off—a common frustration with cheaper bulk screws. The zinc plating adds a layer of protection against rust, making them suitable for indoor and sheltered outdoor applications. Whether you are patching a panel, assembling a guard, or securing flashing, keep a box of Walter 48N024 screws in your shop for reliable, hassle-free fastening.
