Questions & Answers
What size are these ZENITH cup head bolts?
Each bolt is M8 with a 150mm 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 150mm they suit deep timber connections in retaining walls and structural framing.

Customer Reviews
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.

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.
