Whats best 2 hold my 3/4'; fiberboard together 4 my sub box? im afraid nails or screws will split tha wood

Use a bead of wood glue across the entire edge. Use a thin finishing nail (about 2'; long) about every 4 inches. The nails only hold the box together while the wood dries. Most commercial boxes aren't nailed at all, just glued, but they have large clamps to hold the pieces while they dry.Whats best 2 hold my 3/4'; fiberboard together 4 my sub box? im afraid nails or screws will split tha wood
go with some 2 inch sheetrock screws.When you are through use some liquid nails to seal all of the inside cornersand edges,this will help hold everything togather and seal them for air leaksWhats best 2 hold my 3/4'; fiberboard together 4 my sub box? im afraid nails or screws will split tha wood
I completely agree with the above answer. You can easily use screws to put together this type of material as long as you pre-drill it. Make sure you do use at least some sort of sealant, even if it's just 2 sided tape... get a sort of gasket on the seams
2'; or 1 3/4'; wood screws with a wide head. You should drill the holes with a drill bit smaller than the screws first to prevent splitting. Also if you arent cheap, you should get some kind of epoxy ('liquid nail' or such) and glue the seams before putting it together, then run a bead along the seams to prevent air leakage.
