Description & Specs

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.

  • Model name: Hot Dipped Galvanised Black Cup Head Bolts & Nuts

It's ideal for fences, gates, pergolas, decks and retaining walls exposed to the elements.

A matching nut is included.

Questions & Answers

What size is this cup head bolt?

It is an M10 bolt measuring 75mm in length, supplied with a matching nut.

Is it suitable for outdoor projects?

Yes. The hot dipped galvanised finish offers strong corrosion resistance, ideal for fences, gates, pergolas and other weather-exposed structures.

What does the cup head and square neck do?

The cup head gives a smooth, low-profile finish, and the square neck grips the timber so the bolt does not spin as the nut is tightened.

Should I use a washer with it?

A matching galvanised flat round washer under the nut helps spread the load and protect the timber; washers are sold separately.

What grade of steel is it?

It is made from 4.6 grade steel with a hot dipped galvanised black finish.
