The Zenith M12 x 400mm hot dip galvanised cup head bolt and nut is sold individually for long fastening jobs that need a clean, flush finish. The low-profile cup head sits neatly against the surface and the square neck under the head stops the bolt spinning as you tighten the nut.

  • Finish: Hot dipped galvanised
  • Colour: Grey

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.
