Hi. After about of advice please. I am reasonably new to woodworking and as a "simple" project am in the process of making a table similar to the attached image. The table top will be old oak edge glued with no breadboards or apron ( not yet decided if I will have cleats ) I have made the legs which are 2 x steel X shapes with a steel cross beam between the 2 X intersections for increased stability. There is also a spreader plate at the top of the X of 6mm steel x 80 cm. my question is I am thinking of securing the 6mm x 80 cm spreader plate to the underside of the table by inserting threaded nuts into the underside of the table then bolting through the plate as I thought this would be longer lasting than just putting screws straight into the wood, I'm just wondering if this may cause issues with expansion etc? The table top I have made is is old oak so I'm hoping will not have too much movement in it but just wondering if an expert can see an issue with this method of attaching? Thanks in advance
