metal bracket on hard drive magnets ?

I like to use the holes that are already in the brackets as mounting holes, and I put screws through them and make a row of the magnets on the studs on the wall that my bench sits against. I use them to hold screws in items I am taking apart in order of removal (top to bottom), and also keep the most commonly used bits for my driver their, like phillips and various common sized of torx bits. Keeps them handy, and I can spend more time working and less time looking for the proper bits and tools!
