Angle iron with many holes - optimal holes to put screw in best stabilization?

Submitted by tsn22 t3_y8ttvg in DIY

I have an open bookcase that's extremely clumsy. I got myself two angle irons with which I'll stabilize the bookcase. Angle iron (I have two of that)

Short arm will be drilled into the wall, long arm will be drilled into top of bookcase.

Now obviously I wont be making use all the holes, but I'm thinking of drilling & screwing twice for each arm. I was wondering if there would be a best option in terms of hole selection? Like, would drilling and screwing vertical holes would give me best stabilization? Or horizontal? Or cross? Or am I overthinking this?

Use one hole closest to the bend and then another hole in the opposite row of holes closest to the end of the bracket. Repeat for each flange of the bracket for a total of 4 screws per.

I'd do 1 in the bottom right corner, one in the top left corner, 1-2 in the middle and one in the top.

Just dont use adiacent holes, because in some wall can tend to create fractures and internal damage.

The further apart the screws the better. I agree 2 per arm should be enough to stabilize a bookcase.

I've always found that the holes closest to the bend are hard to get screws in, and later remove them.

I'd be forced yourself all four holes on the short leg, simply because there are only four, so why not use them.

On the long leg, I'd use the two holes at the very tip, and then also use the two holes that are "almost" next to the bend.

If for some reason I felt I needed to add a screw right next to the bend, I'd use a very long extension on the driving bit.

Art is asymmetrical. Just drill in some random screws and give it the security tug “that’s not going anywhere” and call it a day

My suggestion would be to take a piece of 2x1 wood. Cut is to width of shelf. Attach it to bottom of a fixed shelf in the bookcase.

Now if the back of your bookcase is flush against the wall, you are good. If not flush add another piece of 2x1 wood of another scrap.

To finished, just drill into 2x1 into 1 or 2 studs.

If you read the instructions for similar straps by Simpson, they say a fastener goes in every hole. But that does seem overkill especially for the leg supporting the shelf. I would use every hole on the leg to the stud.
