At PowerPro, we've highly engineered our products to be stronger, faster, and the best-in-class, so you can feel confident that you're doing only your best work. Our self-drilling screws are ideal for fastening metal to wood in roofing and metal building applications quickly, but securely. Self-drilling screws are a type of self-tapping screws which are threaded fasteners that drill their own hole and thread it as they are installed. Each screw is made with a Micro-Bit point that acts as a drill bit, one that can consistently drill single or multiple thicknesses of high-strength steel panels. This "drill bit" also requires less end pressure to penetrate metal surfaces and engage the wood. Whether you're working on roofing, metal, cement board, drywall, brick, or wood, PowerPro has the right tools and hardware for the job. PowerPro was founded to provide craftsmen with solutions that complement their hard-earned skills. We understood from the beginning that trust is earned, and never freely given. So, we rigorously designed, tested, and improved our products to ensure that we delivered the unrivaled performance and quality that craftsmen deserve.
