Questions & Answers

What size are these ZENITH cup head bolts?

Each bolt is M6 with a 100mm 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 length connections suit these?

At 100mm they suit deeper timber connections in framing and outdoor structures.

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 M6 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.
