Why choose 410 stainless self-drilling screws?

410 stainless offers excellent strength with reliable corrosion resistance, making these screws suitable for both indoor and outdoor projects. The self-drilling tip eliminates the need for pre-drilling, saving time, while the hex washer head provides a secure seal and a clean appearance in metal-to-metal joints.

Tip: Use a hex driver or bit that matches the head size to ensure proper seating and to avoid stripping. Apply steady, even pressure for best results and control torque to protect the washer seal.
