Truss Head Phillips Self-Drilling Screws 4.2x13mm – Pack of 100

The Truss Head Phillips Drive Self-Drilling Screws 4.2 mm x 13 mm (#8 x 1/2″) – Pack of 100 are designed for professionals and DIY users who require reliable fastening with maximum efficiency. Featuring a wide, slightly rounded truss head, these screws provide excellent surface coverage, ensuring a secure and flush fit without damaging delicate materials. The Phillips drive design is self-centering, offering better grip and torque transfer while reducing the risk of cam-out or slipping.

Crafted from high-quality tempered steel, these screws are zinc-plated for superior rust resistance and long service life. The self-drilling tip eliminates the need for pre-drilling, allowing the screw to cut through sheet metal, steel, and other surfaces effortlessly. This feature not only saves time but also ensures precise and clean installations, making them a cost-effective solution for large-scale projects.

These screws are widely used in construction, roofing, and fabrication. They are ideal for securing polycarbonate sheets, shadow covers, brick ties, roof decks, and accessories to steel framing. The truss head distributes load evenly, making them suitable for applications where holding power and stability are critical.

Installation is straightforward: simply insert the screw into a hex or Phillips head adapter, position the tip against the material, and apply steady pressure with your drill. The self-drilling point finds its center quickly and drives smoothly, ensuring a strong and reliable hold. Once the head tightens against the surface, stop drilling to avoid over-torquing.

Whether you’re a professional contractor or a DIY enthusiast, these 4.2mm x 13mm truss head self-drilling screws offer the perfect combination of durability, convenience, and performance. With a pack of 100, you’ll always have the right fastener for your next project.
