Meet the Teks 12 x 2-3/4 inch Wood-to-Metal Self-Drilling Screws, a 40-piece pack built for fast, secure wood-to-metal assemblies without pre-drilling. Engineered for reliability where wood meets steel, these screws deliver a strong hold in demanding outdoor and trailer applications.

• Self-drilling performance: The combined drill-point and flute remove material efficiently and pre-size the hole for self-tapping threads, letting you drive straight into wood and metal with a single tool.
• Wood-reaming wings: Special wings ream a clean hole in the wood to prevent thread engagement during drilling, reducing pre-tap resistance and giving you smoother installs.
• Star Drive, zero cam-out: The star head drive provides maximum contact during installation for reduced stripping, even under high-torque driving with a drill or impact driver. T25 bit sold separately.
• Corrosion-resistant Climaseal coating: Built to resist rust in harsh environments, making them ideal for roof decking, subfloors, trailer beds, and headers on steel frames.
• Versatile installation: Use with a drill or impact driver to speed up fastener cycles on large projects—from roof decking to trailer bed assemblies.
• Practical compatibility: Sized at #12 with a 2-3/4″ length to maximize grip in typical decking and frame thicknesses; sold in a 40-piece pack for long jobs.

Ideal for installers, DIYers, and professionals tackling projects that mix wood and metal. If you’re building or repairing a trailer, upgrading a roof deck, or attaching wood headers to a steel frame, these screws provide dependable hold, easier installation, and long-lasting durability thanks to Climaseal coating.
