Questions & Answers
What size are these ZENITH cup head bolts?
Each bolt is M12 with a 200mm length, supplied with matching nuts in a 12 pack.
What is hot dip galvanising?
It is a thick zinc coating applied by dipping the steel in molten zinc, giving strong corrosion resistance for outdoor and exposed use.
What does the cup head and square neck do?
The rounded cup head finishes flush against the surface, and the square neck beds into timber so the bolt does not spin while you tighten the nut.
Are the nuts included?
Yes, matching hex nuts are supplied with every bolt in the pack.
What are these bolts used for?
They suit timber framing jobs such as decking, pergolas, retaining walls and fences where a long M12 fastener is required.
