Product Description

These Metal Construction Heavy Section Screws offer engineered performance when you need to attach metal to structural steel without the hassle of pre-drilling. The hardened carbon steel tip slices through heavy steel while the A2-304 stainless steel body resists rust and corrosion in outdoor and industrial environments. The hex head ensures strong grip and torque compatibility with standard tools, letting installers work faster and cleaner. Silver organic coating adds weather protection, keeping the screws looking sharp and holding strong over time. Reliable load bearing and long lasting performance make them ideal for construction, agricultural, metal fabrication and exterior building projects.
