Lorna, made a good point and I’d like to add a thought. If you don’t know what something is called but know what you need it to do, or what you need done go to a good hardware site, and browse until you find what you need.
Then you have a base price and the exact name of the item, so from there you can do a search and find a better price, free shipping, an auction, or what ever.
It takes a lot of time but it really works
