410/304/316 Stainless Steel torx drive flat head self drilling screw
Stainless steel 410, 304 and 316
StainGrip® 410 / 304 / 316 Stainless Steel Torx Drive Flat Head Self-Drilling Screws are high-performance structural fasteners engineered for flush-surface mounting, fast drilling, and high holding power in wood-to-metal, composite-to-metal, sheet metal, and aluminum framing applications. Available across multiple stainless steel grades—including heat-treated 410 for maximum piercing hardness, as well as SS304 and marine-grade SS316 for ultimate corrosion protection—these screws feature a countersunk flat head and deep Torx drive for smooth, slip-free installation.
Key Features & Technical Benefits
Versatile Stainless Steel Options (410 / 304 / 316 Grades):
410 Stainless Steel: Heat-treated to achieve extreme surface hardness, enabling the screw to pierce and tap directly into structural steel framing without snapping or dulling the drill tip.
304 & 316 Stainless Steel: Delivers outstanding, long-lasting resistance against rust, outdoor weathering, chemical exposure, and marine saltwater environments.
Countersunk Flat Head (Smooth Flush Finish): Sinks neatly flush into pre-countersunk holes or softer material surfaces, providing an unobstructed, smooth finish without raised edges across metal panels, timber boards, and equipment assemblies.
Deep Torx Drive System (Optimal Torque & No Cam-Out): Precision-molded star drive recess ensures superior bit engagement, allowing high torque transmission while completely eliminating driver bit cam-out, slippage, and head stripping during high-speed driving.
Precision Self-Drilling Tek Point: Integrated drill bit tip drills, taps, and fastens into steel, aluminum, and composite materials in a single step, eliminating the need for pre-drilled pilot holes and speeding up installation times.
Full-Length Deep Threads: Precision-formed self-tapping threads provide continuous engagement along the full length of the shank, delivering high pull-out resistance and long-term joint integrity under vibration.
