The Jack L-Shape Reinforcing Foundation Bolt anchors objects firmly to concrete slabs. This longer M12 x 300mm bolt has a 90-degree angled leg that sets deep into the slab so the bolt holds fast under load.

  • Thread size: M12
  • Length: 300mm
  • Shape: L-shape (90-degree leg)
  • Material: Steel
  • Finish: Galvanised

The angled leg keeps the bolt from pulling away from the slab, making it ideal for securing bulky items such as sheds. The extra 300mm length suits deeper or higher-load fixings, while the galvanised coating helps it stand up to outdoor conditions. A nut is included for fastening.

Satisfied customer

Had been looking at the Jack L-Shape for a couple of months. Jack 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 Jack L-Shape 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.

Best buy of the year

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.
