From the image, these small curved metal pieces look like furniture connector plates / curved joining brackets (also called corner braces, mending plates, or crescent connector plates).
They are commonly used in woodworking and furniture assembly.
What are they used for?
These pieces help join or reinforce wooden parts, such as:
- Chairs and tables
- Cabinets
- Bed frames
- Wooden boxes
- Shelves
- Furniture repairs
The holes are for screws or bolts. The curved shape allows them to fit around corners or curved joints while adding strength.
How they work:
- The metal plate is placed over a joint between two wooden pieces.
- Screws are inserted through the holes.
- The plate holds the pieces together and prevents movement or cracking.
Why are they curved?
The curve gives them extra strength and lets them sit neatly against rounded edges or corners. It also spreads pressure over a wider area compared with a straight flat strip.
The coin in the picture helps show the size:
They appear to be small hardware pieces, likely used in DIY furniture repair or manufacturing, rather than a household gadget.
If you found a bag of these, they may have come from:
- A furniture assembly kit
- A carpenter’s hardware collection
- A factory/repair workshop
If you can show the other side or any markings stamped on them, I can help identify the exact type.
