Description & Specs

The Zenith M12 x 150mm hot dip galvanised cup head bolt and nut is a 4.6 grade steel fixing made for outdoor construction where corrosion resistance matters. The hot dip galvanised coating shields the steel from rust, so it holds up well in fences, gates and other exposed timber work.

  • Bolt size: M12 x 150mm
  • Head type: Cup head
  • Material: 4.6 grade steel
  • Finish: Hot dipped galvanised
  • Colour: Grey
  • Includes: Bolt and matching hex nut
  • Pack: Each

The low-profile cup head sits flush for a tidy finish, while the square neck under the head locks into timber to keep the bolt from spinning as the nut is tightened. The coarse thread grips strongly for fastening timber to timber, metal to timber or metal to metal.

Outstanding value

Bought this on a bit of an impulse after seeing it on the site and really glad I did. Quality is much better than the price suggests — feels premium and well made. Ordered Monday and it arrived Wednesday in Sydney. Nothing loose or damaged. A few people have asked where I got it.

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.
