Choosing a dome nut
Choose the material and finish for the environment: stainless for corrosion resistance, galvanised for outdoor use, chrome for a bright finish, and nylon where you want a non-metallic, snag-free cap. Make sure the nut is long enough to cover the bolt end. Always check the data sheet for the thread, size and grade of the exact nut before you order.

Dome Nut FAQs
What is a dome nut used for?
A dome nut covers the end of a bolt or threaded rod. It protects the thread, hides the cut end and removes a sharp edge that could snag or cut.
Is a dome nut the same as an acorn nut or cap nut?
Yes, in general use these names describe the same style of closed-end nut.
Can a dome nut take a structural load?
A standard dome nut is a finishing nut. For a load bearing joint, check the grade on the data sheet and confirm with the engineer.
