Great corrosion resistance
Living near the coast, rust is a big concern. These 410 stainless screws have held up perfectly over the last few months.

Solid value for money
Works as expected. Just make sure your drill has enough torque for thicker steel sheets. Good bulk pack.

Good quality, fast shipping
The stainless steel quality seems solid. One star off because the box was slightly dented upon arrival, but the screws were fine.
