  • 6Deck Drive

    not among the top performers

Corrosion After Acid

  • 1Grip Rite

    coating held up the best yet, no visible corrosion

  • 2GRK

    coating experienced quite a bit of damage but no visible rust

  • 3Spax

    metallic coating makes assessment hard, but appears to be in great shape

  • 4Deckmate

    coating destroyed by the acid but no visible rust

  • 5WoodPro

    no visible rust, looks about the same as Deckmate

  • 6Deck Drive

    acid ate away the coating but no rust

  • 7FastenMaster Guard Dog

    coating scrapes off easily but no visible rust

  • 8PowerPro

    acid removed most of the coating but no visible rust

  • 9Deck Plus

    part of the coating removed by drilling into oak but no visible corrosion

  • 10Velocity

    experienced quite a bit of corrosion compared to the other brands, worst performer on this test

  • 11Eagle Claw

    acid and salt caused some corrosion on the first screw tested, but a second screw tested with only the rusting agent experienced very little corrosion

How it was tested

  • torque required to drive the screw
  • coating condition after driving into a pressure treated 4x4
  • coating condition after driving through 1 inch oak into a 4x4
  • impact driver install speed
  • shear load using an AR500 metal shear tester
  • holding strength pulling the screw out of a 2x4
  • downward force needed on a drill press to start the screw
  • corrosion after 1 hour in sulfuric acid plus hydrogen peroxide, vinegar, and salt rusting agent

I like the Grip Rite. It came out on top with an average finish of 2.4, but I also like the GRK and Spax.
