Questions & Answers
What size are these ZENITH cup head bolts?
Each bolt is M6 with a 40mm length, supplied with matching nuts in a 25 pack.
Is hot dipped galvanised the same as galvanised?
Both add a zinc coating, but hot dip galvanising gives a thicker layer for 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 are these used for?
They suit decking, fencing, retaining walls and general timber framing.

Customer Reviews
No complaints at all
Exactly as described. Quick shipping. Would buy again.
Works perfectly out of the box
Was exactly what I needed for the price I paid. Arrived well packaged and was easy to set up straight away. Already recommended it to a friend who is also thinking of getting one.
Worth every cent
Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.
