Concrete screws in practice – What can ATLANTIS-coated INDEX concrete screws do?

When fixing takes more organising than you would like

A bracket, a mounting rail, then the next fixing point. Installation runs smoothly when you know in advance which fastener, tool and work process it requires.

If the chosen system involves a curing time, it has to be built into the schedule. If it only turns out on site that the screw length or head form is wrong, another round of coordination and purchasing may follow.

That is why it is worth stating the installation task, the thickness of the part to be fixed and the environment together, already in the quote request. That way the purchase is based on the actual task.

What does a concrete screw add to the workflow?

Direct thread engagement in the concrete

The special thread bites into the wall of the pre-drilled hole. No separate anchor or adhesive is needed for the fixing. The concrete screw is a low-expansion solution; the permitted edge and spacing distances must still be observed.

Installation overview in three steps

1. 1

   Drilling.

   Follow the hole diameter and hole depth specified for the selected screw.

2. 2

   Hole preparation and setting.

   Treatment and any necessary cleaning of the hole, as well as the tool and its setting, are defined by the manufacturer’s installation instructions.

3. 3

   Checking.

   Check for proper seating and the specified embedment depth.

This overview does not replace the product’s installation instructions.

What kind of work is it worth considering for?

Brackets and supports, shelving and racking systems, timber-to-concrete connections, railings and temporary installation solutions. Suitability is always decided by the load and the documentation of the specific product.

Look at data you can base a decision on

A product name alone is not enough for a good choice. For the ATLANTIS-coated versions of the INDEX TH family, the manufacturer provides technical data sheets, ETA documents, a declaration of performance and installation information.

Worth requesting together for the selected product

• Exact item number and technical data sheet.
• The ETA and declaration of performance covering the application.
• Installation instructions and the data needed for design.

That way the decision is based on the selected product and the actual use.

Which concrete screw suits the task?

Start with the connection: what are you fixing, what surface does the head have to bear on, and how much room is left for the tool?

Manufacturer version

Selection criterion

THE – hexagon head

If access is suitable for a spanner or socket wrench.

THA – countersunk head

If the part to be fixed has a suitable countersink and a flush head is required.

THP – pan head

If the connecting part calls for this head design; check the head and hole size.

THT – truss head

If this flatter, wide head form suits the connection; check the bearing surface.

The right length takes more data than the plate thickness

State the thickness of the part to be fixed, as well as every intermediate layer or gap. The screw length and the applicable embedment depth must be selected from the specific product’s table. The required hole depth is a separate figure.
