A: While not considered a structural screw, 3rd part testing has an allowable shear strength of 369lbs. Thanks for being a SPAX customer!
A: Yes they are
A: Yes, that is what I use them for, in several sizes.
A: Nope, you need an outdoor screw for the coating for pressure treated woods. There are so many chemicals in that mess it will eat indoor screws in no time.
A: Yes. Although I would go with a larger size.
A: That should be no problem, depending on how the screws are installed. I would suggest HCRX coated SPAX because of better corrosion resistance
A: Hello, For an exterior application, we would recommend you use our HCR-X coated screw. The HCR-X coating is better suited to deal with weather although both coatings, Yellow Zinc and HCR-X, are ROHS compliant. Thank you for being a SPAX customer!
A: I use them in my organic garden. I'm sure there's a zinc coating on it, it's not solid I don't think. The amount of zinc or other metalloids that would leach off of it yearly would do nothing, actually, as it breaks down and goes back into the soil you'll add a few minerals. Your boards will rot before that of course :) Use cedar, no salt treated. But the zinc itself will absorb into the soil. Happy plantings!
A: Yes. Gqlvqniz d to prevent rusting
A: Can't say for sure but wouldn't think so. The plating is zinc which is harmless - even beneficial. These are tough screws. They really grab.
A: Deckmate uses T25 drive... MUCH SUPERIOR to the T20 used by Spax
A: these are T20 I believe
A: DeckMate person, the Spax products are all structural rated, deck screws are not. Superior with Spax.
