The cost-efficient concrete screw for high installation ease.

Concrete screw FBS 5 SK

The fischer concrete screw FBS 5 SK is made of zinc-plated steel with a countersunk head and a torx. The FBS 5 SK is perfectly designed for applications like fixings of channel systems, surface-mounted sockets, or electrical installations and plumbing in general, as well as in DIY. When the concrete screw is screwed into the drill hole the thread flanks cut deep into the base material, therefore ensuring load-bearing capacity. The low drilling effort saves time during the installation. The recommended loads for concrete as well as the suitability in masonry, like soli sand-lime bricks and classification into fire resistance class R 120 guarantee safety.

Advantages

Quick and easy assembly and disassembly using a cordless screwdriver, tangential impact wrench or manual installation.
The recommended loads for cracked and uncracked concrete make the application more secure.
The concrete screw FBS 5 offer the possibility for use in masonry, like solid sand-lime bricks, for a flexible use in different substrates.
Two embedment depths enable high flexibility for example for plaster bridging and a precise adaption.
Fire resistant values according R120 enable the use in case of fire.
The sawtooth geometry enables fast cutting into the base material.
The expansion-free anchorage system (undercut) enables low edge and axial spacings.
The concrete screw in diameter 5 is ideal for the installation of cable routing, surface-mounted sockets or in general non-safety-related applications that require relatively little load.

Applications

Eletrical installations
sanitary, heating and air conditioning installations
Surface-mounted sockets
Cable Clamp
Cable trays
Channel systems
Light wall cabinets
Picture frames

Building materials

Recommended loads for:

Concrete starting at C20/25 to C50/60, cracked and non-cracked

Suitable for:

Masonry out of solid building materials with a dense structure, such as solid sand-lime bricks

You can find detailed information on building materials in the approval document.

Functionality

The concrete screw FBS 5 SK is recommended for the push-through installation.
We recommend using a tangential impact screwdriver with a suitable impact screwdriver socket, or a cordless screwdriver or manual installation by hand.
Drill hole cleaning is necessary.
The screw is installed correctly when the screw head sits flush on the fixture and cannot be screwed in deeper (visual setting control).
