I have a nice set of allen wrenches with big handles, which are very convenient, but have always hidden away in a drawer, and all clung together like plastic monkeys whenever I wanted to get one out. Last week I installed a new cabinet in my little shop, and thought "What a perfect spot to hang the Allen wrenches!" The screws supporting them have large enough heads to keep them from falling off the doors, but when the doors are swung open they all rattle and crash as they swing in and out. Yesterday I was into Princess Auto, and picked up a pack of 8 small magnets for less than $3.00 for the lot. I put a dab of glue on the back of each one, slid it in place under an allen wrench with the glued side against the cupboard door. The magnet held itself in place untill the glue dried, and now I have great storage, right up front where I want it, and they don't rattle and crash about when the doors are opened and closed.
