FISCHER screw anchor 503787 — pack of 4, metal/chemical anchor sleeve H 12 x 85

The FISCHER screw anchor 503787 is a pack of four metal injection anchor sleeves FIS H 12 x 85 designed for mortar-based installation of threaded rods or internal threaded anchors in perforated brick masonry. The sleeve works with compatible FIS injection mortars and features an optimized lattice structure that reduces mortar consumption while creating a mechanical interlock between the mortar and the masonry. The product supports pre-positioned installation and can bridge non-load-bearing layers when used according to the mortar approvals.

Advantages

The lattice structure of the anchor sleeve lowers the amount of injection mortar required and improves transfer of loads into perforated brick. Centring blades secure different rod diameters, reducing system complexity and simplifying storage. A barbed hook design prevents falling during overhead installations. The sleeve is approved for use with relevant FIS injection mortars.

Suitable for

• Anchoring threaded rods or internal threaded anchors in perforated brick masonry
• Mortar-based chemical anchoring using compatible FIS injection mortars
• Pre-positioned installations where the sleeve is set before mortar injection
• Applications requiring bridging of non-load-bearing masonry layers

When it may not be suitable

This anchor sleeve is intended specifically for use in perforated brick and with compatible injection mortars; it is not suitable for solid masonry types unless explicitly approved. Structural or safety-critical applications require verification of mortar approvals, design values and applicable ETA or local approvals before use.

Key specifications

• Type: metal injection anchor sleeve with lattice structure
• Size: 12 mm diameter x 85 mm length
• Pack quantity: 4 sleeves
• Material: metal sleeve (compatible with chemical injection mortars)
• Suitable mortars: FIS V, FIS VW HIGH SPEED, FIS VS LOW SPEED, FIS VL, FIS Green, FIS P Plus, FIS P

How to use

Drill the hole to the specified diameter and depth, clean according to the mortar manufacturer’s instructions, insert the anchor sleeve in pre-position, inject the approved FIS mortar into the sleeve and surrounding voids, then install the threaded rod or internal threaded anchor so the mortar is pressed through the lattice structure to form a mechanical interlock with the perforated brick. Follow the curing time and load instructions of the chosen injection mortar and the product approvals.

What to consider before purchase

• Confirm compatibility of the chosen FIS injection mortar with perforated brick and the sleeve
• Ensure the 12 x 85 mm sleeve dimensions match the threaded rod or anchor to be used
• Verify that the sleeve and mortar approvals meet local codes and project load requirements

Usage recommendations

Use the FIS H 12 x 85 anchor sleeve with recommended FIS injection mortars, perform thorough hole cleaning, and adhere to the mortar curing times and ETA approval conditions to achieve designed load capacity in perforated brick masonry.
