The Zenith M10 x 75mm Hot Dipped Galvanised Black Cup Head Bolt and Nut is made for outdoor structural fastening on thicker timber. The smooth dome cup head sits low for a clean look, while the square neck under the head locks into the timber to stop the bolt spinning while you tighten the nut.
It's ideal for fences, gates, pergolas, decks and retaining walls exposed to the elements. The longer 75mm length suits thicker joints, and the hot dipped galvanised coating gives strong corrosion protection across timber-to-timber, metal-to-timber and metal-to-metal connections. A matching nut is included.
