Very good screws. Light and good quality. We've used them to hold 1x4 pine boards and they're perfect. The packaging from the supplier was insanely good. I don't know why it's only good for screws, but it is. Unfortunately, we counted several boxes that seemed "light" and only found 129 screws in each. Still worth the money but you can buy extra in advance. Our project stalled because we were expecting about 145 screws in a box and there weren't any, so at the end of our project we had to stop and order more screws and then wait for them to arrive. Good product and definitely worth the money compared to some cheap ones.
