Description & Specs

The Zenith M10 x 240mm Hot Dipped Galvanised Cup Head Bolt and Nut is a single, extra-long 4.6 grade steel coach bolt for deep structural fixing.

  • Bolt size: M10 x 240mm
  • Head type: Cup Head
  • Material: 4.6 Grade Steel
  • Finish: Hot Dipped Galvanised
  • Pack quantity: Each (nut included)

The low-profile cup head gives a flush finish, while the square neck bites into the timber to limit the bolt spinning as you tighten the matching nut. The coarse thread builds strong grip, and the hot dip galvanised coating adds corrosion protection for outdoor use. The long 240mm shank reaches through thick or stacked timber sections for retaining walls, sleepers and heavy structural work, and is sold individually.

Satisfied customer

Had been looking at the Zenith M10 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 M10 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.
