Hex Flange Self Drilling Screw: All-in-One Fastener for Industrial & Construction Needs

For engineers, construction teams, and metal fabricators, time and reliability go hand in hand—and our Hex Flange Self Drilling Screws deliver both. These all-in-one fasteners drill, tap, and secure in a single step, eliminating pre-drilling and reducing labor costs. With a built-in flange for superior load distribution and a hex head for easy torque application, they’re the top choice for metal-to-metal, metal-to-wood, and composite fastening across automotive, construction, and industrial sectors worldwide.

What Is a Hex Flange Self Drilling Screw?

A hex flange self drilling screw (also called a hex washer head self drilling screw) is a specialized fastener that integrates three functions: drilling, tapping, and clamping. It features a hexagonal head (for secure grip with wrenches or power drivers), an integrated flange (acts as a built-in washer to distribute pressure and prevent pull-through), and a self-drilling point (equipped with a drill-like tip to penetrate hard materials). Unlike standard self-tapping screws, it doesn’t require pre-drilled pilot holes, making it ideal for high-volume, time-sensitive projects. The flange design also eliminates the need for separate washers, streamlining the fastening process.
