Self-Drilling Truss Head Screws – #8 Phillips (3/4″, 1 1/2″)

#8 Phillips Truss Head Self-Drilling Screws (3/4" & 1 1/2")

When your exhibit design calls for metal stud framing, aluminum extrusions, or attaching materials to metal structures, these self-drilling truss head screws are a show-site essential. Designed specifically to penetrate metal without the need for pilot holes, these fasteners keep your I&D team moving fast and efficiently.

Available in two essential lengths (3/4" and 1 1/2"), this variable listing covers the most common metal-fastening needs in trade show fabrication. Use the compact 3/4-inch length for standard metal-to-metal joints, such as framing modular walls or assembling light boxes. Step up to the 1 1/2-inch length when you need to fasten thicker materials, like plywood backing, plastics, or Sintra, directly to a metal frame.

The low-profile truss head (also known as a modified truss or wafer head) provides an extra-wide bearing surface. This acts like a built-in washer, preventing the screw from crushing delicate surface materials or pulling through thin lath and wire mesh. Because we supply these factory-direct by the pound, you get exactly the bulk quantities you need for your custom builds.

Key Features for Exhibit Builders:

• Self-Drilling Point: The specialized drill point bites into and threads metal studs and frames in one fluid motion, eliminating the time-consuming step of pre-drilling.

• Extra-Wide Truss Head: Provides a massive clamping surface that securely holds thin, brittle, or soft materials without tearing through them.

• Low Profile Finish: The domed head sits incredibly low, making it easy to cover with graphics, SEG fabric, or vinyl applications without unsightly bumps.

• Variable Sizing for Metal Fab: Choose 3/4" for flush metal-to-metal framing, or 1 1/2" for securing panels and rigid substrates to your metal structures.

• Show Floor Ready: An absolute lifesaver for rapid on-site assembly, custom structural modifications, and quick fixes at the convention center.
