Mazel E-Z Driver yellow zinc deck screws drive fast with a T25 star recess that resists cam-out, while the heavy-duty zinc dichromate coating stands up to outdoor exposure. The sharp Type-17 auger point self-starts without pre-drilling and helps prevent wood splitting. Rated for all treated lumber, including ACQ, making them suited for decks, fences, sub-flooring, and exterior framing.

Tip: Use a T25 star/Torx bit - the 6-lobe pattern transfers far more torque than Phillips and almost never strips out. Yellow zinc dichromate is best for indoor or covered exterior service; for fully exposed wet or coastal installs, step up to stainless or polymer-coated structural screws.
