SX 4 x 20 K NV - fischer fixings

fischer Expansion plug SX 4 x 20 with rim

The powerful nylon fixing with four-way expansion, with rim for optimum hold.

Art.-No. 90886

Top Features

Optimum force transmission due to four-way expansion. This allows for high holding values in solid and hollow building materials.
Simple to assemble: The edge of the plug prevents it from falling deeper into the drill hole.
No expansion pressure on the plug neck. This means that tiles or plaster are not damaged.

Product Description

Due to four-way expansion, the fischer expansion plug SX optimally transfers forces into the building material. The high-quality nylon used in production and typical expansion guarantee a secure, permanent connection. The edge on the head of the fixing prevents the fixing from slipping into the drill hole. The fischer expansion plug SX is the best choice for fixing, e.g., lights, strips, bath and toilet installations, as well as lightweight wall cupboards.

Advantages

The 4-way expansion provides the optimum force distribution in the material, and offers high load-bearing capacities in solid and hollow building materials.
The expansion-free plug neck prevents the creation of expansion forces on the material surface whilst screwing in the screw. This helps to prevent damage to tiles and plaster.
The pronounced rim prevents the plug from slipping into the drill hole, thus allowing for a simple installation.
The greater anchorage depth of the SX 6x50, 8x65 and 10x80 means that the plug is especially suited to fixings in hollow building materials, aerated concrete and to bridge plaster.

Assembly Instruction

Functionality

The SX is suitable for pre-positioned and push-through installation.
When turning in the screw, the SX expands in four directions, thus providing a secure anchoring in the building material.
The required screw length is given by: Plug length + fixture thickness + 1 x screw diameter.
Suitable for wood, chipboard and spacing screws (fischer ASL, see page ).
