lumber brace edge distance minimum for lag screws?

lumber brace edge distance minimum for lag screws?

lumber brace edge distance minimum for lag screws?

(OP)
I will be using a diagonal brace similar to this picture. I only have very minimal axial loads on the brace.
So the brace size and bolts will be minimum. This guide from FEMA doesn't show the edge distance and bolt distance.

I plan on using 1"x6" for the diagonal brace but not sure if I will meet the minimum edge distances required.

Also I'm used to using 3/4" dia bolt as minimum for steel in my industry.
What is the minimum bolt diameter you will use in this case (lumber/timber) brace?


RE: lumber brace edge distance minimum for lag screws?

I wouldn't be bothering with using a 1x6, those aren't worth anything structurally. 2x6 or bigger. The edge and end distances you want to know about are in the NDS.

RE: lumber brace edge distance minimum for lag screws?

Yup, buy the NDS if you are doing wood design.

I will use 2x8 .. 2" edge distance and 4" bolt distance.. and 1/2" dia lag screw.. this should be good..

RE: lumber brace edge distance minimum for lag screws?

I'd opt for galvanized spikes, maybe 4. Stagger the locations.
