I want to hang two shelves in the laundry room above the washer and dryer. The shelves are 2x12's that are 60" long. I bought a pair of heavy duty brackets (11 5/8" x 8 1/4") rated to 1000 lbs per pair. My plan is to use 2 brackets per shelf and secure them to the studs. I'll use 6 x 1 1/4" interior screws to attach the shelf to the bracket. I'm at a loss for what fastener to use to attach the brackets to the studs. I have 1/4-2 3/4" exterior Power Pro screws. I'm worried these might be too long. Maybe I should use 1/4-2 1/4" screws instead. The bracket is 1/8" and the drywall is 1/2".

My main questions are, how do I choose the right fastener? Also, does this plan make sense? The previous shelves fell down recently (the previous owners hung them with drywall anchors), and I have a feeling my brackets are overkill, but I want to avoid any crashes in the future for us or future owners.

EDIT: I hung the shelves. 1/4-2" lag screws into studs with 3/32" pilot holes. 3 lag screws per bracket. Brackets are rated to 1000 lbs. per pair. I connected the shelf to the brackets with 1-1/4" screws. I even hung on them for good measure and everything looked good.

Thank you to everyone for your advice! It was very helpful. Picture of installed shelves is below.

    That's some... serious overkill! On the bright side, you now have a place for extra guests to sleep!

Those brackets and shelves should do just fine. The nominal length for screws into studs is 1.25". A stud is 3.5" thick. 1.25" from each side allows for up to 1" in the middle to run wires or plumbing. 1.25" + 0.5" (drywall) + 0.125" (bracket) = 1.875" or 1-7/8". 1-3/4" or 2" should also be just fine.

I would not recommend 1-1/2" (not enough holding power) or 2-1/4" or longer (risk of damage if there are wires or pipes in just the wrong place).

Yep, I think the shelves are over designed but they sure won't fall down. you only need 3/4" screws to fasted the shelves to the brackets and use 1/4-2" for mounting the brackets to the studs. Just make sure you hit the center of the studs.
