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
  • Model number: BGBC1075
  • Bolt size: M10 x 75mm
  • Material: 4.6 grade steel
  • Finish: Hot dipped galvanised black
  • Head type: Cup head
  • Pack: Each (bolt and 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.

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.

Outstanding value

Bought this on a bit of an impulse after seeing it on the site and really glad I did. Quality is much better than the price suggests — feels premium and well made. Ordered Monday and it arrived Wednesday in Sydney. Nothing loose or damaged. A few people have asked where I got it.

Satisfied customer

Had been looking at the ZENITH M10 for a couple of months. ZENITH build quality is obvious as soon as you open the box — feels solid and well finished. Easy to set up and works exactly as described. Delivery to Perth in only 3 days which is impressive. Will be buying more from SuperSaver AU for sure.
