Concrete screws are high performance anchors, designed to withstand high loads and ensure fast installation in cracked and non-cracked concrete.
Here are some of the advantages of concrete screws compared to controlled expansion anchors:
- Concrete screws can be removed once it has been installed, meanwhile controlled expansion anchor can’t be removed (sometimes, controlled expansion anchors can be cut, inserted into the hole in which they are installed u other remedies that hide it but, they never can be removed).
- Diameters 5 and 6 of concrete screws are homologated for concrete and, moreover, are homologated for hollow core slabs for non-estructural systems.
- Most of the times, concrete screw anchors let us to install it in a less thickness of concrete and less distance between edges than controlled expansion anchors, for example:

| THE (Concrete screw) ETA 20/0046 | SLPT (Controlled Expansion) ETA 18/1108 |
- The installation for this anchor, for a medium-experience user, is considerable faster if we compared it against a controlled expansion anchor so, if we need to install a lot of anchors in our construction site, the effective time is going to be reduced a lot. Moreover, we don’t need a high number of tools, only a drilling machine and an impact gun.
- Concrete screw for diameter 10 is homologated for three different embedment’s (reduced, intermediate and standard) this is going to give us a lot of versatility due to the fact that only using one length of anchor we can fix it in three different lengths.
At INDEX® we have concrete screws approved for structural and non-structural applications, offering a variety of head and coating options to suit your needs.
