The Zenith M10 x 75mm Hot Dipped Galvanised Cup Head Bolt and Nut is a single 4.6 grade steel coach bolt for securing timber structures.
The domed cup head sits low for a clean finish, while the square neck bites into the timber to stop the bolt spinning as you tighten the matching nut. The heavier M10 diameter and 75mm length suit solid structural joins, and the hot dip galvanised coating adds corrosion protection for outdoor use. It is well suited to fixing timber to timber and timber to metal in decks, fences and pergolas, and is sold individually.

Great quality
Good quality and arrived ahead of schedule. Very happy.
Brilliant Aussie deal
Been buying Zenith gear for years and this is one of their better ones. The Zenith M10 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.
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.
Does the job well
Zenith quality is always reliable and this was no exception. Fast delivery too.
