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

  • 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.

    As always, great stuff! With an upcoming exterior project to be completed, I will definitely be using deck screws to hold my untreated Hemlock board. I love this channel, I check it a couple times a day looking for more informative videos. Keep up the great work.

    I would believe that the twisted nail would perform better if the apparatus wasn’t allowed to twist. That would be closer to real life IMO.

    I noticed when the nails were hit in at a slight angle there had the most holding power and the ones that were straight down they had the lease amount of holding power

    I think the fact your jig was able to rotate was an issue for the spiral nail. In a deck the top piece of wood would not be able to rotate

    Would of liked to see length of screws testing? Do 2 2” screws hold the same as 1 4” screw?

    The holding power of a spiral shank is when it does not spin.

    You didn’t test the spiral shank properly your basically unscrewing it ...that needed to be pulled out without twisting

    So what you’re telling me is that screws are better than nails(I already knew this) but if i have to use nails I should used galvanized coated. I was surprised of how much force it takes to pull a nail out

    I find it amazing and hard to imagine that literally a single nail could support the weight of a grown person, and five screws could hold up a car!

    Shear strength, yes. But also, perhaps, an off-axis pull or something where the fastener bends during the pull? I've found that some screws let go on off-axis use. They tend to be very brittle in the transition zone between the threads and the shank, implying either excess work hardening or a non-tempered state. These are inexpensive commercially available screws and nails, so one wouldn't expect tempering as one would expect in a grade 8 bolt. This video had a great set of tests, very well thought out and performed. Oh, one little criticism. The "d" in their sizing callouts is termed "penny", as in a 16 penny nail.

    you didn't include square nails. while i agree the with screws findings, square nails are supposed to be amazing.

    huh i would have thought that the ring shank wouldve needed to sit and let the wood swell back into the rings to get its bite
