Questions & Answers
What size are these coach screws?
They are M12 thread by 50mm long.
What does hot dip galvanised mean?
The steel is dipped in molten zinc to form a thick, rust-resistant coating ideal for outdoor use.
Can hot dip galvanised steel be welded?
It can be welded, but the zinc coating should be removed from the weld area first and the area re-coated afterwards, as welding over the zinc affects the join and produces fumes.

What are they used for?
They are used for heavy-duty construction, fastening timber to timber or metal to timber such as retaining walls, sleeper walls and fences.

Customer Reviews
Highly recommend
Really impressed with the Zenith M12 — it looks and feels more premium than the price suggests. Delivery was quick and packaging kept everything safe. No issues at all.
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 M12 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.
