Concrete screws in practice – What can ATLANTIS-coated INDEX concrete screws do?
Read more →: Concrete screws in practice – What can ATLANTIS-coated INDEX concrete screws do?A concrete screw cuts its own thread into a pre-drilled hole: no separate wall plug, no expansion, no curing time, and it can be dismantled again.

An even more powerful bond with INDEX® chemical anchors
Read more →: An even more powerful bond with INDEX® chemical anchorsWith a chemical anchor the resin bonds the base material and the fixing element along the entire hole: no expansion force, no cracking, and an even load distribution that works close to edges too. The polyester MO-PU Universal covers general fixings, while the MO-V Vinyl Ester takes on structural loads.

Anchor bolts
Read more →: Anchor boltsTwo ways to anchor into concrete and stone: the internally threaded drive-in wedge anchor, which a wedge expands along its slot, and the ring anchor bolt, which grips harder the more you tighten the nut. Both in NONOX stainless (A2) and acid-resistant (A4), M6 – M24, available from stock.
