410 Stainless Steel Flat head Torx drive self drilling screw
Heat Treated SS410
StainGrip® 410 Stainless Steel Flat Head Torx Drive Self-Drilling Screws are high-strength, heavy-duty fasteners engineered for fast piercing, flush countersinking, and maximum structural holding power in wood-to-metal, composite-to-metal, or sheet metal applications. Manufactured from heat-treated 410 stainless steel, these screws combine extreme surface hardness and shear strength, enabling them to drill, tap, and fasten into steel and aluminum sub-framing in a single operation.
Key Features & Technical Benefits
Heat-Treated 410 Stainless Steel (High Strength & Hardness): Hardened through specialized heat treatment to deliver exceptional hardness and tensile strength, allowing the screw to pierce structural steel and aluminum without snapping, binding, or stripping threads under heavy torque.
Precision Self-Drilling Tip (Tek Point): Features an integrated drill bit tip that effortlessly drills through metal joists and framing without requiring pre-drilling, drastically cutting down installation time and job-site labor.
Countersunk Flat Head with Underhead Nibs: Designed with a classic flat head equipped with self-countersinking underhead nibs that cut a neat recess, ensuring a perfectly smooth and flush finish without surface tearing or splintering.
Deep Torx Drive System: Precision-molded star drive recess ensures optimal driver bit engagement, delivering maximum torque transmission while completely eliminating driver bit cam-out, slippage, and head stripping.
Enhanced Corrosion Protection Coating: Treated with an advanced exterior protective finish to resist moisture, outdoor exposure, and environmental corrosion during heavy-duty outdoor structural builds.
