Perhaps due to my inattention, I thought that these very small items were only sold in packages of 10.

Just as expected. Steel anchor nut. Rivet hole size is 3/32

Nut, One Lug Anchor MS21051L06

Small footprint. Dimensionally stable. I have found these to provide snug vibration-proof bolt retention. Excellent for brackets and paired backing plates where a nut would be difficult to single handedly tighten.
