Which Type of Nail or Screw Has the Most Holding Strength? Let's find out!

Loading...
  • Published on: 25 March 2019
  • The difference in holding strength among different types of nails and screws is amazing! The type of coating used on nails and screws makes a huge difference. In the video, 5 types of nails and 2 types of screws get tested for tensile strength in untreated 2x4s. Each type of fastener is tested 7 times and the highest and lowest strengths for each fastener is "thrown out". The types of nails include 16D coated, uncoated, galvanized, spiral shank, and ring shank. The types of screws include 3.5 inch drywall and coated deck screws.

    I’m curious if fastener gauge would have made any difference since a larger fastener would have a larger surface area? Great video. Had no idea galvanization made so much difference.

    Good info, I noticed that it takes more pulling force to pull nails or screws that were nailed down at a slight angle. Thanks

    Hello, I really admire your videos and I know it’s a lot of work to make them all. Congratulations, continue with your useful content on YouTube, because every day has more useless content.

    I think that it can do better with harder wood because the wood break before it came up

    Anyone else notice the first nail set tested he labeled the the 4th one as 4rd?

    Wouldn't the spiral nails hold a tremendous amount of additional force if the testing environment didn't allow the piece to rotate, as I imagine it wouldn't realistically in any environment where the wood is long and attached to other pieces of wood? This test makes spiral nails look a lot weaker than they are in practice -- I would believe.

    That pretty much mirrors my experience. I’ve only yanked a couple deckmates, but plenty of drywall screws and ring nails and the crowbar makes your hand ring when they finally let go.

    I use mason nails you don't pull them out if you can pull them out the wood is very poor

    My only concern I have with the test is using a natural material like wood that can vary in its density making it easier or harder to remove. Using a man made material like Trex that is uniform would provide a uniform test media.

    Please do a shear strength test on the same thing

    so i know this is long after this video was posted, but i wonder if the spiral shank nail would have done better if your rig wouldnt have spun as it pulled the nail out?

    I don’t get it. It’s a screw of course it has more holding power than a nail. More tread on the nail the better!!

    But when i use the deckmate, they are so easy to strip the hole out when driving them in; they are very good if they dont strip out

    Those twist nails wont come out you had to twist them out, try pulling one straight out the head will break off, you have to cut twisted nails off 90% of the time to get something apart they are stronger than screws, screws are good for pulling wood together tight but still use nails it will make it even stronger.

    So 3 deck screws can hold up a 3000lb car? Geez

    That's when you have bigger deck screw.. tested and proven..

    This guy's clearly never shoveled a Canadian driveway. Cleared a 100mm of snow Saturday night. Cleared another 150mm Sunday morning.

    Wonderful analysis! Loved watching the tests and the results were pretty cool

    Spiral shank was miss represented due to you jig twisted with the spiral creating a miss represented score you should create a jig that doesn't twist you noob

    Deck nails you need more than just 1 for them to hold. You can really compare them to other nails unless you do all the tests with 2 hammered in.

    Stainless 304/316 is the only option for true corrosion resistance.

    something to note that you may have missed is that the zinc galvanized nails did have corrosion. it was the zinc that was corroding, which left the white powdery look on the nail (zinc oxide), instead of the iron.

    since most framers use strip nails this test with different collated nails would be great.

    I think it is erroneous to test framing nails using pulling force when framing nails are always used in shear.

  • Charlie Swails

    The nails and screws should be drilled / hammered in at the same depth bc of the nail was deeper it would be harder to pull put
