These clips are useful for so many things in the studio: clipping together components that will be riveted together so that they don’t get separated, holding items together temporarily before securing in a ring clamp in anticipation of drilling them or sometimes even clipping paperwork and receipts together. These clips are very cheap (about 59 cents each) and I found them in Home Depot, in the “tool jail” near the much larger and much more expensive clamps. You can buy them by the dozen and will almost never be sorry that you have more lying around all over the place. Sometimes a person needs to spend some money. Just a little bit.
