Its durable finish ensures reliable performance in all weather conditions, from coastal roads to city streets.

Technical Review

Manufactured from galvanised or stainless steel, the Hex Dome Nut is built to withstand prolonged exposure to moisture, salt, vibration, and mechanical stress. It’s the preferred choice for securing backing rails, RSJ clips, faceplates, and other roadside components while protecting fastener threads from corrosion or debris.

Its domed design discourages unauthorised removal, making it especially suitable for use in public or high-risk locations. Easy to install with standard tools, the Hex Dome Nut is a small but vital part of a secure and compliant road signage system.
