Description & Specs

The Zenith M12 x 170mm hot dip galvanised cup head bolt and nut is a 4.6 grade steel fixing for outdoor construction where rust resistance is important. The hot dip galvanised coating protects the bolt and nut, so it suits retaining walls, gates, fences and outdoor furniture.

Perfect gift — loved it

Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.

Great value for money

Spent a while looking for the right Zenith M12 and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.
