Attaching shelves and 2x4's to studs and joists.

[lowcountry]

Need to attach shelving that is 1/2 plywood and 2x4's to wall and ceilings with sheetrock. I assume lag bolts would be best? Any size or other fastener type suggestions?

Regular drywall screw 1 5/8-2” coarse thread

That wont reach the stud. I like to use 3” deck screws

Remove the 2x4s and use these:

Anchored to the wall with deck screw or stronger.

I did this across an entire wall in my garage and was SHOCKED at the load I could put on the system.

With the uprights, the loads on the screws is more "down" than "out", as you'd get with a 2x4 frame under the shelf.


Yes, it adds a not-insignificant cost to the project, but it works great, and you can change height, or add "mid-shelves" for smaller items and bins.

I want to use French Cleats for ease of moving things around.

I have been using deck screws, but wouldn't mind a little more arse.

what’s the sheet rock screw to then. Sounds like you may have some horizontal furring attached to the studs

Hes talking about putting 2x4s on top of drywall and attaching them to the studs behind. gonna need more than a sheet rock screw for that.

This is correct. I find it easier to just mount a 2x4 horizontally for mounting and hanging in the garage instead of only relying on studs locations.

DO NOT use drywall screws.
They are brittle and with not support a load.
Use the anchor screws, expensive but worth the cost.

I used torx drive #10 deck screws 2.5 - 3". My shelving is plenty strong enough for the load + me (200#) climbing up it. Sheetrock screws are phillips drive and as mentioned before, are brittle. I use short sheetrock screws to hold the thin plywood decking down to the 2x4 shelf frame.

Headlock.

You’re welcome.

Yep.... this.

Make sure the joists in the ceiling are solid wood in stead of the engineered I beam.

You are going through 1 1/2" of 2 x 4 plus another 1/2" of sheetrock. I wouldn't use anything less than a 3" screw. 3 1/2" would be better. The Headlocks are good, though.

HeadLoks are considered structural fasteners. Use the appropriate length and an impact driver to sink them.
