12pcs M8 Solid Half Moon Nuts Washer Spacer Furniture Hardware Accessories for Furniture Connect (Length 27mm x Width 14mm), Silver

We like that these are metal! The ones we replaced were plastic and they broke in half. The metal ones worked great!

The specifications state these are fully threaded. They are not. I couldn't tell by pictures but some pictures so threads and state it isn't threaded so I looked for a product that stated it was. Disappointed I wasted time.

These are great just what I needed for the wood bed frame thank God they're solid and not chintzy like the ones that came with it
