SS304 Square Drive US Standard Pan Head Self-Tapping Screw 10GA × 12-50 A2

Product Features
304 Stainless Steel for Corrosion Resistance and Durability: Made of A2 austenitic stainless steel with a self-passivating anti-rust layer, it resists moisture and mild acids/alkalis. With no coating to peel off and no risk of hydrogen embrittlement, it is suitable for long-term use in both indoor kitchens/bathrooms and outdoor environments, while being environmentally friendly with no heavy metal contamination.
Square Drive for Non-Slip Torque Transmission: The internal square recess provides tight bit engagement, preventing slippage during power driving and reducing recess wear. It withstands high torque and is well-suited for automated mass assembly; it also offers a basic tamper-resistant effect, as standard cross-type tools cannot remove it.
Pan Head for Easy and Attractive Installation: The broad radiused flange head clamps workpieces firmly without crushing the substrate, and eliminates the need for countersinking; after assembly, the smooth, rounded head has no sharp edges, avoiding scratches to workpieces or personnel.
Multiple Sizes for Versatile Applications: The #10GA standard coarse thread with sharp point offers moderate penetrating power; available in lengths from 12–50 mm to match thin sheets, multi-layer panels, and thicker profiles for secure fastening.
