NDS Table 11K Question
(OP)
I have 1/2" dia lag screws going through a 3/16" plate into a beam and I am trying to determine the shear strength of the screws.
NDS Table 11K only gives values for my plate thickness up to a 3/8" dia screw. Do I use that value even though my screw dia is larger?

You can use it for lags, bolts, wood screws and nails.
Main member matl (wood) is chosen from a pull down menu, as is side member, which includes steel up to 1/4". (Steel is the top choice in the pull-down menu and you may have to scroll up to it.)
I've checked the output to hand calculations for three different cases (for all 6 yield modes) and I always get the same answer within a percent or 2. It is a huge timesaver.
