Dome Nuts (Acorn / Cap Nuts) – Metric BZP Zinc Plated Steel (M5–M12)

Dome nuts — also called acorn or cap nuts — in bright zinc plated steel, sized M5 through M12. The closed dome caps the end of a bolt or threaded bar for a neat, safe finish with no exposed thread.

Material
Zinc plated steel

Finish
Bright zinc plated (BZP) for corrosion resistance

Thread
Metric coarse pitch

Standard
DIN 1587 hexagon domed cap nut

Finish & safety
The closed (blind) dome covers the bolt end, hiding sharp threads and giving a tidy, finished look

Sizes
M5, M6, M8, M10 and M12

Uses
Furniture, handrails, garden and marine fittings, and any exposed bolt or threaded-bar end where appearance and safety matter

Good to know
The dome is closed, so the bolt shouldn't be longer than the nut's internal thread or it will bottom out before tightening
