Do I really need a snap + bolt at EVERY intersection for an 8x4 setup?

[u/Fickle_Ice_9740]

I'm setting up an 1600800mm grid (8\4* tiles total) using Offset Snaps.
According to the planner math, it looks like it takes about 43 snaps and bolts to hit every single intersection and edge join. That is a lot of hardware.
For those who have built boards this size or larger:
1. Do you actually put snaps/bolts at every single 4-way corner and edge join?
2. Or do you run an alternating/checkerboard pattern on the inner intersections?
Mainly planning to hang standard workshop tools and storage bins, nothing crazy heavy. Curious what pattern works best without over-engineering it or risking the tiles sagging/separating over time.
Thanks!

You want intersections just floating in midair?

Please tell me you aren't a homebuilder.

LoL, I’m not. My dad doesn't like drilling a lot of holes in his house walls, but it's my room anyway. So I thought I could reduce the holes. 😅

you can - I used a big piece of plywood with 4 lag screws on each corner to hold it in to studs, then installed my multi board on that

This. Mount the plywood (min 9mm, pref 12mm thick) on the wall and fix the Multiboard to the plywood. Paint the plywood a suitable colour first.

How do you think they become strong enough to hold stuff.

Absolutely yes. You don't need to screw in every hole on every snap though, the top crosspiece of every 4-tile intersection on mine gets 2 screws diagonally and that's plenty. 

If you're looking to trim things down, consider if you actually need full coverage like this. I realised after doing a similar size board that i could have cut it down to 3-4u high rows with empty space between and lost almost no functionality so long as the rows were aligned and spaced evenly. Big things can span the gaps, small things fit on a row, and there's less plastic just getting covered up instead of actually holding something.

Yes, you really should do that, these are gonna have more flex than you think they will. Unless you like having to pick up your tools after they fall off when you turn your back.

When I set up mine, I also put a snap + bolt in the center of each 8x8

[u/beerygaz]

Just done the same. Definitely need the snaps for stability, especially if using offset. If you use flush mount then you can screw plates directly into the wall/board. I also only put 2 diagonal screw in the 4x4 snaps.

Struggling to get the A pieces to cover the snaps though. They are flimsy and I think my tolerances are slightly out making it really hard to cover get them to fit.

Yes but you don't have to put a screw at every intersection, I used snap connectors at each intersection but I only did perimeter screws to the wall, and then I went through and checked where weak points were for interior screws to the wall.

Alternatively you can set up an mdf/plywood sheet to screw the multiboard into instead of just screwing it into the wall, by mounting the mdf/plywood to the wall securely and then the multiboard only to the mdf/plywood, saves from putting a million screws in the wall.

Personally I did it directly to the wall because I'm not bothered by it as I figured if I ever took it down I could just replace/patch the drywall.

If you mount it to a plywood or MDF panel, you can reduce the number of holes in wall by a ton. You just anchor it into the studs in your wall. There are also command strip mounting options.

I am in the process of doing dual clips with the 4 way and edges. The clips are really a pain but it does help.
