FISCHER screw anchor 522836 – injection anchor sleeve set, 4 pieces

The FISCHER screw anchor 522836 is an injection anchor sleeve set (4 pieces) designed for mortar-saving installation of threaded rods or internal threaded anchors in perforated brick masonry. Used with compatible fischer injection mortars, the sleeve's optimized lattice structure reduces resin consumption by allowing the mortar to be pressed through the mesh and form a mechanical interlock with the base material. The sleeve also permits pre-positioned installation and can bridge non-load-bearing layers when the approvals of the chosen injection mortar are respected.

Advantages

The anchor sleeve's lattice structure lowers the amount of injection mortar required while creating a secure form fit in perforated brick. Centring blades accommodate different rod diameters to simplify handling and storage. A barbed hook prevents the sleeve from falling out during overhead work. The product is supplied as a set of four sleeves and is compatible with a range of fischer injection mortars for flexible use.

Suitable for

• Anchoring threaded rods or internal threaded anchors in perforated brick masonry
• Installations using fischer injection mortars (e.g., FIS V, FIS VW HIGH SPEED, FIS VS LOW SPEED, FIS VL, FIS Green, FIS P Plus, FIS P)
• Pre-positioned installation and bridging of non-load-bearing layers
• Construction and installation tasks requiring reliable load transfer in hollow masonry

When it may not be suitable

Not intended for use without a compatible injection mortar; approvals for the specific mortar must be checked before installation. The sleeve is designed specifically for perforated brick and may not achieve the same performance in solid concrete, natural stone, or other non-perforated substrates.

Key specifications

• Format: injection anchor sleeve set, 4 pieces
• Designed substrate: perforated brick masonry
• Function: mortar-saving lattice structure for mechanical interlock
• Compatibility: suitable for use with recommended fischer injection mortars
• Installation type: pre-positioned installation; suitable for bridging non-load-bearing layers

How to use

Choose a compatible fischer injection mortar and follow the mortar manufacturer's instructions and approvals. Drill the hole to the required diameter and depth for the sleeve, insert the injection anchor sleeve in a pre-positioned manner, inject the resin so that it is pressed through the lattice structure, then insert the threaded rod or internal threaded anchor and allow the resin to cure according to the product data sheet before applying load.

What to consider before purchase

• Verify that the chosen injection mortar is approved for use with perforated brick and this sleeve
• Confirm the sleeve dimensions and compatibility with the threaded rod or internal threaded anchor you plan to use
• Ensure the substrate is perforated brick masonry; performance differs on solid or other materials

Usage recommendations

Use with fischer injection mortars specified for hollow masonry, adhere to the curing times and load values in the mortar approval, and follow standard drilling and installation practice to achieve reliable anchoring results.
