bolting my box???

[Based]

Ok so for a few months now the box for my 4 15s has been sitting on bricks to even it out. I'm tired of it moving around and **** so I'm doing wooden blocks now. The only question I have it what would you guys recommend doing as far as bolting goes?

My idea is to do a hex bolt going from the bottom of the floor into the bottom of the block and then have a bracket that will have a bolt going through one end of it on the wooden block's side and then another bolt going into the side of the box. The only problem is I don't know what this type of bracket is called....

So yeah any recommendations are welcome thanks!!

just screw the blocks to the box then bolt it to the floor

you can even hold it down with a ratchet strap. doesn't really matter

Any bracket you would probably need you can find made by Simpson Strong Tie. The HD carries them in the deck section along with joist hangers and other structural ties/brackets. They are strong and galvanized and relatively cheap. Then you can mount it nicely.

When using a bolt like this:

Do I need to tap the threads or do I just drill and screw?

That type of bolt requires threads or a hex nut. The thickness of whatever you screw it into should be at least the diameter of the bolt. Not good for wood or sheetmetal.

For screwing into wood you'd use a lag bolt:

1/2 in. x 3 in. Galvanized Hex Lag Screw-803966 at The Home Depot

For sheetmetal you'd use sheetmetal screws but they'll be smaller and you'd use a bunch of them.

Lags are sufficient, these are the best. Much more expensive though.
