Hi all,

Just wanted to pose a question to a group that would be far more experienced at this sort of thing.

I am in the process of building a live edge dining table and bench for my family. My slabs are approx 2.5” thick Douglas Fir.

The bench legs are 1/4” steel which is 3” wide (see attached) and will have 8 holes (4 at each end) to affix the legs to the table/bench.

I will be attaching metal legs in due course and am curious the size of screw to use. Is there a big difference between using #8 and #10 from a strength perspective? One better than the other?

Any insight would be most appreciated.

Thanks in advance!

Personally, I would use 2” #10 screws. They will hold better and won’t cost significantly more. Remember to elongate the holes through the steel because the wood will expand and contract with seasonal humidity changes and the steel won’t. FWIW

Whenever I’m in doubt, I go 1/4’. Something like this should work – – your countersink should be about 1/2” radius with a depth of about 1/8”
