This is a pack of 60 tiny compression springs. They're basically little metal coils that push back when you squish them. The specs are: 0.22 inches in outer diameter (OD), the wire itself is 0.02 inches thick, and the spring is 1.6 inches long when it's relaxed (not compressed). They're made from steel and have a silver zinc-plated finish to resist rust. What do you use them for? All sorts of little repair jobs or DIY projects. They're common in things like retractable pens, small toys, battery compartments, screen door mechanisms, scales, or any gadget that needs a bit of push-back tension. Having a pack of assorted small springs is a lifesaver when you're trying to fix something and find a broken spring. These are all one size, so if this size matches what you need, this bulk pack is great value. They come in a little bag. Handy for hobbyists, tinkerers, or just anyone who likes to keep spare parts around.
