Deck Blocking and Bridging: The Only Guide You'll Ever Need

Should You Nail or Screw Deck Blocking? To fasten deck blocking 10d nails are commonly used. Nails have greater shear strength and screws greater pulling and holding ability. Some builders use specially designed and manufactured structural screws instead of nails to pull twisted joists against the blocks and to prevent squeaks.

Structural vs. Lag Screws - Bright Hub Engineering

29-10-2010·Structural screw design is more complicated than lag screw design because structural screws are driven through the construction material themselves, without the use of a pilot hole. Some screws have mini-drill bits attached to the end, which helps clear wood as the screws are being drilled in. Structural screws are good in shear, having typical maximum allowable shear of about 250 to 400 …

Nails vs. Screws: When to Use Each Kind of Fastener

17-11-2020·Shear strength refers to the ability of a fastener or other construction element to withstand lateral, or side to side, pressures: Think of wind blowing against a house. This is where nails excel. Even if the pressure becomes extreme, they will bend rather than snap (as screws often will as they are typically made of hardened steel).

16-07-2017·They calculated a correction factor: the estimated composite shear strength should be multiplied by a factor of 0.85 for connections with more than seven screws. So in your example, three screws each with 1,000 lb. shear strength will have a combined shear strength of 3,000 lbs. and support a 2,000 lb. load.

Wood Handbook, Chapter 08: Fastenings

The strength and stability of any structure depend heav-ily on the fastenings that hold its parts together. One prime advantage of wood as a structural material is the ease with which wood structural parts can be joined together with a wide variety of fastenings—nails, spikes, screws, bolts, lag
