#10 X 1/2" Self Drilling Sheet Metal Screws - 410 Stainless Steel 100pc

These #10 x 1/2 inch self-drilling screws are absolute game-changers for metalworking projects! Made from 410 stainless steel, they're perfect for damp environments and won't rust like regular steel screws would. The best part? They eliminate the need for pre-drilling holes - the built-in drill point cuts right through materials up to 0.176 inches thick. The modified truss head design provides a larger bearing surface that won't pull through thinner materials, and the Philips P1 drive is super common so you probably already have the right bit. With a tensile strength of 180,000 psi and hardness of 40 Rockwell C, these aren't some flimsy hardware store screws - they're serious fasteners that can handle demanding applications. The package includes 100 pieces, which is perfect for larger projects or keeping your workshop stocked. The spaced threads (Type BSD design) help with chip removal and create strong threads in the materials you're fastening. Whether you're working with sheet metal, HVAC ductwork, metal roofing, or any thin gauge metal applications, these screws make the job so much faster and easier. No more switching between drill bits and screwdriver bits - just position the screw and drive it in. The stainless steel construction means they'll hold up well outdoors or in humid conditions without corroding. The wafer head design sits flush without countersinking, giving a clean finished look. If you do metal fabrication, automotive work, or any DIY projects involving sheet metal, having a box of these self-drilling screws on hand will save you so much time and frustration compared to traditional drilling and tapping methods.
