I am getting ready to install some oak treads. everything is ready to go. I was planning on gluing and nailing them to the stringers. Is this a good way? What size finishing nail do I need to use? Maybe not as big of one since I am gluing them too? thanks.

 

Both, with a long enough nail to grab.

 

My personal suggestion is to use Torx Bit TRIM Screws (Small Diamater Head) *They usually come with the Torx Bit in the box of screws*...

(3) per stringer on the tread ( Total) and (3) per stringer on the risers (9 Total).

I would also suggest using a PL Construction Adhesive - PL-400 (or equivalent). Nailing is "acceptable", but screwing / glueing the treads and risers into place will give you more stability OVER TIME. You are LESS apt to have sqeaks and creaks!! DRY FIT THE TREAD AND RISER FIRST, THEN PUT THE ADHESIVE TO THE STRINGER (ABOUT A 1/4"-1/2" BEAD) THEN LIFT THE TREAD (OR RISER, WHICHEVER YOU ARE INSTALLING) UP AND DOWN ABOUT 3-5 INCHES 5-6 TIMES.; This will air activate the adhesive, and your treads and risers will be assured a tight bond.

Also, start at the bottom with the first riser. Cut the riser about 3/16" short of the top measurement (so the tread, when installed, does not touch the top of the riser) but keep it tight to floor below...

Then install the first tread, holding the tread BACK from the stringers about 3/16"). The riser that gets installed next will butt down ONTOP of the tread you previously installed and that way the tread, if at all, can flex without rubbing against the stringers or riser. Continue this right up to the top.

Good luck with your project...
