Yeah, I use them too, with the plates, I have done a lot of retro-fit, strengthening on my house.. I'm talking about general framing, just 3" screws. Sadly in the US code folks think all screws are drywall screws. Code people can't seam to adapt to the idea of screws/clamp load, they just want to continue to think about shear of nails. Thus still have to go back thru and put nails in too.
The boxes are way too few, screws per package, why they don't sell them in bigger containers just doesn't make sense. Plus their re-designed cardboard box design is awful.
