Screw capacity in wood
WebbThe capacity of connections with closely spaced, large diameter bolts has been shown to be limited by the capacity of the wood surrounding the connection. Connections with groups of smaller diameter fasteners, such as typical nailed connections in wood-frame construction, may not be limited by wood capacity. WebbCoach screws also called lag bolts or Lag screws in the USA are a large wood screw with a hexagon or square drive. Lag bolts are designed for securely fastening heavy timber beams and posts along with timber railway trestles and …

A typical range for proof strength for steel is 50 to 100 kpsi (i.e., a screw with a 1 square inch cross-sectional area of steel can hold up to 50,000 to 100,000 pounds). See here and here. Of course, as the diameter of your screw increases, the stud is likely to fail first. Share.
