Questions & Answers

What size are these ZENITH cup head bolts?

Each bolt is M8 with a 90mm length, supplied with matching nuts in a 25 pack.

How thick is hot dipped galvanising?

Hot dip galvanising leaves a thicker zinc coating than standard plating, giving stronger corrosion resistance outdoors.

What does the square neck do?

It beds into timber so the bolt does not spin while you tighten the nut.

Are nuts included?

Yes, a matching hex nut is supplied for every bolt.

What length connections suit these?

At 90mm they suit deeper timber connections in framing and outdoor structures.

Brilliant Aussie deal

Been buying Zenith gear for years and this is one of their better ones. The ZENITH M8 quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.
