A premium coated deck screw tuned for corrosive treated lumber, worth the upcharge on a deck you want to last.
Pros
- Quik Guard coating is engineered for today's more corrosive ACQ/treated lumber
- 6-lobe T-25 recess and underhead nibs countersink cleanly with almost no cam-out
- Backed by Simpson Strong-Tie's structural-hardware reputation and consistent quality control
Cons
- Costs more per screw than generic bulk deck screws like DeckMate
- Coated, not stainless, so still not the pick for marine or ground-contact use
- Mostly stocked in #10 x 3 in and up, so thin trim work needs a different size
