Skruvankare Fischer 41900 50 mm

The fischer plastic injection anchor sleeve FIS H K is a system component intended for use with fischer injection mortars in perforated brick masonry for through-type installations. The anchor sleeve is inserted into the drilled hole and filled with injection mortar from the sleeve base. When the threaded rod or internal threaded anchor is set, the mortar is pressed through the sleeve's lattice structure and forms a mechanical interlock with the perforated brick, transferring loads into the base material. The sleeve geometry also enables bridging of non-bearing layers.

Advantages

The lattice structure of the FIS H K anchor sleeve is matched to fischer injection mortars such as FIS V, ensuring economical mortar use and an effective interlock. Centring blades align the anchor within the sleeve and permit use with different threaded rod diameters. Barbed hooks secure the sleeve in the drilled hole and enable reliable overhead installation. The sleeve geometry supports bridging of non-bearing layers for easier installation in through-type masonry.

Suitable for

• Fixing threaded rods and internal threaded anchors in perforated brick with injection mortar
• Through-type installations where loads must be transferred into masonry
• Situations that require bridging of non-bearing layers (e.g., plaster or hollow spaces)
• Applications compatible with fischer injection mortars (for example FIS V)

Key specifications

• Product: fischer injection anchor sleeve FIS H K (plastic)
• Compatible mortar: fischer injection mortars (e.g., FIS V)
• Recommended use: perforated brick masonry, through-type installations
• Pack example (related product): Screw Anchor Fischer 41900 — plastic, Ø12 mm, length 50 mm, pack of 50 (EAN 8001132419007)

How to use

Drill the hole to the required diameter and depth for the chosen sleeve and base material. Insert the FIS H K anchor sleeve into the hole until seated. Inject the appropriate fischer injection mortar through the sleeve base, ensuring the sleeve lattice fills with mortar. Set the threaded rod or internal threaded anchor; during insertion the mortar will be pressed through the lattice, forming the interlock with the perforated brick. Remove any excess mortar and allow the mortar to cure according to the mortar manufacturer's instructions before applying load.

Recommendations

Use the FIS H K sleeve only with compatible fischer injection mortars (for example FIS V) and follow the mortar and anchor manufacturer's instructions for drill diameter, embedment depth and curing time. For overhead or safety-critical applications, verify suitability via product documentation or calculation software and follow applicable building regulations.
