Concrete screw anchor CLS-I CE Bossong

What it is

The CLS-I CE concrete screw anchor by Bossong is a mechanical anchor in galvanised steel with a hex head and internal thread, designed for applications in cracked and uncracked concrete. Certified for heavy loads in civil and industrial settings, it delivers high performance thanks to seismic category C1 qualification and fire resistance. The standard 6 mm diameter and the availability of several lengths make it versatile for fixings in variable thicknesses, ensuring stability and durability over time.

A concrete screw is a screw anchor that is driven directly into the hole in concrete or masonry, cutting its own thread, without a plug.

What it is for

Used for anchoring shelves, brackets and structures to walls and for structural fixings, where the fixing is load-bearing and must be calculated.

How to use it

Drill with a bit of the diameter specified for the screw to the required depth and clean the hole thoroughly. Drive the screw through the part being fixed with a spanner or impact driver until it is seated, without overtightening. Observe the edge distances and hole spacings stated in the technical data sheet.
