The Zenith M12 x 75mm hot dip galvanised cup head bolt and nut is a 4.6 grade steel fixing built for outdoor construction where corrosion resistance matters. The hot dip galvanised coating protects the bolt and nut from rust, so it suits fences, gates and other exposed timber work.

  • Head type: Cup head
  • Material: 4.6 grade steel
  • Finish: Hot dipped galvanised
  • Colour: Grey
  • Includes: Bolt and matching hex nut

The low-profile cup head sits flush for a neat finish, while the square neck beneath the head grips timber so the bolt does not spin as the nut is tightened. The coarse thread offers strong holding power for fastening timber to timber, metal to timber or metal to metal.

Satisfied customer

Had been looking at the Zenith M12 for a couple of months. Zenith build quality is obvious as soon as you open the box — feels solid and well finished. Easy to set up and works exactly as described. Delivery to Perth in only 3 days which is impressive. Will be buying more from SuperSaver AU for sure.

Absolutely love it!

Had the Zenith M12 on my wishlist for a few weeks and finally pulled the trigger. Arrived in 2 days which was a nice surprise. Build quality is solid and exactly what the photos showed. My partner uses it every day now and has already asked me to grab another one as a gift.

Ordered Thursday and had it by Saturday. Packaging was really good — nothing moved around. Works exactly as expected and the price was well below what I saw in stores.
