A fastener is a device that attaches one thing to another or holds something in place, whether it's the fastener that secures a baby in her car seat or the fasteners you use to snap your jacket shut.

If you go into a hardware store to buy fasteners, you'll come out with some kind of hardware you can use to fasten things together. Screws, bolts, and nails are all fasteners. Unlike welding and soldering, they're a non-permanent way to connect things. If you do a lot of sewing, you also use a variety of fasteners, from snaps and buttons to Velcro and hooks. A fastener makes things fast, or secure.

If you need a large amout of fasteners, you need to find a good factory in your own nation or just import from China.
