Great Company!

I inadvertently ordered 100 self-tapping screws which ended up being too short and the company handled my return with much kindness and patience especially considering that I can be a lil ditzy sometimes!

Quality screws and quick shipping

Maxx Steelbinder self drilling screws are heavy duty and drill well through 24g roof panels and 11g purlins. Price is great compared to Teks and quality is the same or better.
