Complete DIY novice here so hoping someone can help me.
We have recently moved into a new flat which came with a table. Its legs are not fixed but slot into a hole with the remainder filled up by a plastic cog which is turned to fasten the leg. However, one of these cogs is missing, making the whole thing wobbly, and I cannot for the life of me find out what they are called so I can buy another one. Any suggestions?
