Does reassembly using existing pocket holes weaken the joint, or will the screws grab the threads that are already in the wood and create a tight joint? It will be glued also. Thanks

I would think it should be fine. Especially if you are going to add glue.

I’ve done it,just make sure the joint is tight before you re-screw or you ream the old threads out.

If you are asking about using the same holes created before final glue-up Yes and No depending on type of wood product. If you are using hardwood, don’t seat the pocket screw fully and you should have no problem reusing the hole during final glue-up. Plywood is a different animal and in most cases will not allow for re-use of the pocket hole.

I use pocket holes to augment clamps to keep the glue-up process moving. I dot not rely on pocket holes only for keeping joints tight.

I would think you should be fine but like poster said, depends on wood type.
I don’t like them in plywood and I think this will give you the most trouble rescrewing.

Also +1 on pocket screws = clamps, not permanent joint without glue.

Even when glued, you are usually looking at end grain gluing which is weak.

They have been proven over and over to be one of the weakest joints so always consider use of piece before opting for this type of joinery.

I’ve done it often with both ply and solid wood. If you’re using a good quality ply, you won’t have problems. On the initial assembly, I never tighten the screws all the way down. Get them just barely snug, and then on the final go-around, tighten them all the way. As others have said, use clamps during both assemblies, and add glue during final assembly (although I’ve done plenty of times without glue, and those haven’t failed yet).
