Notes on the safe processing of fischer products
Safety first

¡La seguridad es lo primero!

Los valores de retención (cargas) y las aplicaciones indicados en el embalaje son solo orientativos. Dependiendo del grado de montaje correcto, la calidad del material de construcción en el que se va a fijar, las condiciones de instalación y medioambientales pueden verse influenciados negativamente y, en consecuencia, provocar daños a las personas y a la propiedad. En caso de duda, encargue la fijación a un profesional.

Screw size and load


The holding values (loads) were determined by fischer under optimum conditions, such as drill hole preparation and cleaning, correct installation and the best possible screws in intact and load-bearing building materials and under normal environmental conditions.

If plugs are supplied without screws, the loads apply for the recommended screws with the maximum diameter. Screws with smaller diameters mean lower loads.

Building materials and loads

The building material plugs are fixed into is decisive for the load that can be borne by the plug. The building material symbols show which building material groups the plug can be used for. The respective loads are maximum recommended loads in the respective base material.
If several building materials are shown in combination, the load is specified for the weakest building material.

Cracked concrete

Non-cracked concrete

Solid brick

Perforated brick

Solid sand-lime brick

Perforated sand-lime brick

Gypsum plasterboard

Gypsum fibreboard

Wooden boards


Insulation material

Fastening points and loads

Tensile load

The load specified on the packaging only applies for one fastening point (single plug) and represents the lower value of tensile and transverse load.
Tensile load 15 kg (150 N)
Transverse load 25 kg (250 N)
Load specification on packaging 15 kg (150 N)

Tensile load

Transverse load

If the application involves groups of plugs (groups of 2, 4 etc.), the load-bearing capacity of the products must be considered differently. In cause of doubt, we recommend consulting a specialist (see below for support services).

Transverse load

Sujeción de cargas en movimiento

Las cargas en movimiento suponen un reto especial para los productos de fijación.
Antes de fijar una carga móvil con uno de nuestros productos (por ejemplo, columpio/ hamaca/...)
