I used these T30 star drive screws to install stairway railings in my workshop, and they worked perfectly. I countersunk some 4x4s and bolted them into the floor beams along the side of the stairway using these screws, and they held up incredibly well. These screws are strong and made the installation process smooth and secure.
The large washer head provided a solid grip, ensuring the screws didn’t sink too deep into the wood. Plus, the rust-resistant coating gives me peace of mind that they’ll last, even in a workshop environment. If you need reliable, sturdy screws for heavy-duty projects like this, these are definitely the way to go!
