Stainless Steel Dome Nuts M3–M10 — A2 Hex Acorn DIN 1587
Stainless Steel Dome Nuts M3–M10 — A2 Hex Acorn DIN 1587
Why choose these Stainless Steel Dome Nuts
Our Stainless Steel Dome Nuts are manufactured from A2 (18/8) stainless steel to DIN 1587 — the European standard for hex acorn nuts. The closed dome conceals the bolt thread for a clean, finished appearance and protects hands and clothing from sharp ends. A2 grade gives excellent corrosion resistance for indoor and most outdoor environments, including damp and coastal-adjacent settings.

- M4 / 4mm — joinery, brackets and enclosures
- M5 / 5mm — furniture, fencing and panel work
- M6 / 6mm — handrails, signage and general fabrication

Pack options
Each size is available as a 1-unit sample, or in packs of 2, 4, 10 or 20. Use the variation selectors above to choose the exact combination you need. Each nut is inspected before packing.
Typical uses
- Marine and boatbuilding — capping exposed bolt ends on deck fittings, cleats and rails
- Garden furniture, decking handrails and outdoor signage
- Architectural metalwork, gate hardware and balustrades
- Bicycle, motorbike and trailer trim where a finished cap is required
How to fit
Thread the dome nut onto a standard metric bolt or stud and tighten with a hex spanner or socket — the closed top means a torque wrench can be used without marking the cap. Leave 1–2 threads protruding beyond a plain nut and cap with the dome nut, or use a bolt long enough to engage the full depth of the cap.
