Medium-weight sterling silver butterfly nuts (earring back findings) for jewelry making or for replacing lost earring backs. These earring nuts fit all of our sterling earring posts, as well as other 0.027-0.031" diameter (22-20 gauge) posts, which is the standard post gauge range in the United States. For larger diameter posts, hole may be enlarged slightly with a push pin or awl.
