Concrete screws FBS 4 and 5 Fischer

What it is

Fischer FBS 4 and 5 concrete screws are screw anchors with an outer diameter of 5 mm and a length of 50 mm, M6 thread and a hole diameter of 4 mm. The TX25 drive allows precise driving, with an adjustable depth of 30 or 20 mm depending on the thickness to be fixed. They are suitable for concrete class 20/25 and are supplied in boxes of 200.

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 mechanical fixing of structures and components to walls, ceilings and floors.

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.
