My plans call out for SDS 1/4x3, which is a structure wood screw. Can this be used as a substitute?

Asked by bayarea August 27, 2020

I suggest that you compare the performance specs for both the SDS 1/4x3 in. wood screws and these SPEX screws. I believe that the SPEX screws meet or exceed them. I use SPEX Powerlag Screws and SDS screws in various sizes for all of my outdoor construction.

Is this screw available in bigger quantity ?

I love these screws and use a lot of them. They are engineered with spec'd strengths and don't need pilot drilling. This time was even able to order them in quantity so I don't have to go clean out all the local HDs to get what I need....

Worked Great!
I used these screws to attach a fiberglass type product over 2 inch sheets of foam covering the foundation. We put vertical wood strips in the foundation when we poured the concrete, and these screws penetrated the foam and screwed into the wood behind. Much more efficient than trying to put fasteners into the foam itself. I still had to glue the top edge to the foam with a foam adhesive. SO far, it has worked great.
