Collection: Dome Nuts

Dome nuts, also called acorn nuts or cap nuts, have a closed, rounded top that covers the end of the bolt. They follow DIN 1587 and give a neat finish while protecting the thread and keeping sharp ends away from hands and clothing.

Our range runs from M3 to M24 in A2 and A4 stainless, brass, nylon and mild steel, bare or zinc plated. A2 is equal to 304 stainless and suits general use. A4 is equal to 316, contains molybdenum and is the choice for marine and chemical exposure.

Choose a bolt length that does not bottom out inside the dome. For inch sizes, see Imperial Dome Nuts.
