Is it OK to use screws on joist hangers?
While structural nails are typically used to fasten joist hangers, you may be wondering if screws can be used instead. You can use screws explicitly made for joist hangers. However, avoid using any other types of screws as they cannot support joist loads and are not designed to withstand shear force.

The general rule is that two thirds of the length of the screw should penetrate into the lower piece. For example, if the upper piece is 3⁄4” thick, I use a screw that penetrates twice this thickness (11⁄2“) into the lower piece. The total length of the screw should be in the range of 21⁄4“.
How much weight can 2 screws hold?
The easiest way to increase the amount of weight a screw in a stud can hold is to simply double up. If you have room for a second or a third screw, just add more. Two screws can hold 160-200 pounds. Three screws can hold 240-300 pounds.
