Product details and parameters

Hexagon domed cap nuts are often seen in automotive repair shops (for bumpers or engine parts), construction sites (securing metal beams or railings), and furniture factories (assembling tables or fixtures). It is also common in farm equipment, trailers, and public infrastructure like streetlights. This nut is easy to install and has a protective effect on the bolt head.

The hexagon domed cap nut’s design is simple but smart. The hex head gives solid grip for quick tightening, while the dome caps messy bolt ends. Materials like galvanized steel fight rust, and some versions include a nylon insert for extra grip (though not all). It’s slightly bulkier than flat nuts, but that dome adds safety and keeps dirt out of threads.
