The Zenith M6 x 75mm hot dipped galvanised cup head bolt and nut is a 4.6 grade steel coach bolt for fastening timber to timber and timber to metal. The square neck under the dome head grips the timber so the bolt does not spin while the nut is tightened.

  • Brand: Zenith
  • Bolt size: M6 x 75mm
  • Material: 4.6 grade steel
  • Finish: Hot dipped galvanised
  • Head type: Cup head
  • Colour: Grey
  • Pack: Each (bolt and nut)

The longer 75mm shank suits thicker timber sections, and the hot dipped galvanised finish gives corrosion resistance for outdoor decks, fences, pergolas and retaining structures. A matching M6 hot dipped galvanised washer and nut can be added to complete the fixing.

Questions & Answers

Is a nut included?

Yes, each bolt is supplied with a matching hex nut for secure fastening.

Is hot dipped galvanised the same as galvanised?

Hot dipped galvanising provides a thicker zinc coating than standard galvanising, giving stronger corrosion protection.

What timber thickness suits a 75mm bolt?

The 75mm shank is designed for thicker timber sections where shorter bolts would not pass fully through the joint.

Can I fit a washer?

Yes, a matching M6 hot dipped galvanised washer can be placed under the nut to spread the load.

Is it suitable for outdoor use?

Yes, the hot dipped galvanised finish resists corrosion in exterior conditions.

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.
