Good Value

Solid nuts, though shipping took a week longer than expected. Product itself is fine.

Tight Thread

Very secure, sometimes too tight to start by hand but ensures safety once on.

Q: Are washers included in the box?

A: Yes, iron washers are included in the package as described in the product title.
