GALVANISED ACORN / DOME NUTS

Galvanised acorn nuts (also commonly referred to as dome nuts, cap nuts, or blind nuts) are hex nuts featuring a closed, rounded top. The hot-dip galvanised (HDG) finish provides a thick, dull grey zinc coating designed for excellent, long-term outdoor corrosion resistance, making them perfect for timber framing, fencing, handrails, and retaining walls.

• Safety Protection: Enclosing the exposed male bolt threads prevents clothing snags and skin lacerations, especially in high-traffic areas like school playgrounds, public balustrades, and pathways.
• Weather Shielding: The closed dome seals the end of the bolt, protecting the underlying threads from moisture, rust, and debris.
• Clean Aesthetics: They provide a neat, professional, and visually uniform finishing cap to any structural joint
