We are commonly asked in store over the counter, “but which one is the best decking screw…?”
This is the only answer we ever give.
The Amazing Self Drilling, Self Embedding, Self countersinking Wurth Decking Screw!

What are Assy Screws?
Assy Screws offer a high-tech asymmetrical/symmetrical double thread design. The patented AW-drive design combines all the advantages of Phillips, Torx, and Pozi drive bits. The AW-drive is similar to a Torx, but it is tapered, which gives you more contact points inside the head of the screw – enabling accurate screw placement and the “No Come-Out” design prevents screw head damage. The screws also go through an additional annealing process which makes them more malleable.
