Hex Head Self-Drilling Metal Screws 5.5mm x 32mm, Zinc-Plated Tek Screws, Self-Tapping Hexagon Washer Head Fasteners with Drill Point, for Sheet Metal, Framing, Deck, Fence, HVAC and Ductwork (50 pcs)

• One-Step Installation, Self-Drilling Design – These hex head self-drilling screws (also known as Tek screws or drill-point fasteners) feature an integrated drill tip, eliminating the need for pilot holes. Perfect for quick, efficient fastening in sheet metal, thin-gauge steel, and light structural metal assemblies.
• Secure Metal-to-Metal Fastening – Built for heavy-duty performance, these zinc-plated self-tapping screws create strong, vibration-resistant threads in metal. Ideal for HVAC ductwork, metal framing, garage door installations, fencing brackets, roofing, and general steel construction.
• Hex Washer Head for Stability & Load Distribution – The hex drive head offers better tool grip and driving control, while the built-in washer-style flange evenly distributes pressure, reducing pull-through and increasing holding strength on metal surfaces.
• Corrosion-Resistant Zinc Coating – Electroplated for durability, these rust-resistant sheet metal screws are suitable for dry indoor environments and light-duty outdoor use. A reliable choice for long-term installations in residential, commercial, and industrial settings.
• Universal Fit & Tool Compatibility – Compatible with standard 1/4" hex drivers, nut setters, and cordless power drills, these versatile fasteners go by many names: Tek screws, hex head drilling screws, self-piercing screws, or washer head tapping screws. Trusted by professionals and DIYers alike.
