Simpson Strong-Tie's Deck-Drive DSV is a premium coated deck screw tuned for corrosive ACQ/treated lumber, with a Type-17 fast-start point and 6-lobe T-25 recess that countersinks cleanly. Worth the upcharge on a lasting deck, but it costs more than generic bulk screws, isn't stainless for marine use, and stocks mostly in #10 x 3 in and up.
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

Frequently Asked Questions
- Why does treated lumber need a special deck screw coating?
- Because modern ACQ-type treatments are far more corrosive to fasteners than the old CCA lumber. Quik Guard is engineered for that chemistry, which is the main reason to pay more than a generic bulk deck screw.
- Do you need to pre-drill for Deck-Drive DSV?
- No — the Type-17 fast-start point self-taps, and the underhead nibs countersink the head cleanly with almost no cam-out on the T-25 recess.
- Is a coated screw good enough near the ocean?
- No. Quik Guard is corrosion-resistant but not stainless, so marine exposure and ground contact still call for stainless. Note stocking also skews to #10 x 3 in and up, so thin trim work needs a different size.
