FISCHER chemical anchor Aircrete Anchor GB 8, pack of 25, model 050491

FISCHER Aircrete Anchor GB 8, pack of 25 (model 050491) is a chemical anchoring solution formulated for use in aerated concrete and comparable lightweight substrates. The system is designed to secure threaded rods and bolts, creating load-bearing connections with high pull-out resistance and long-term stability. Supplied as a batch of 25 anchors, this product is intended for construction, installation and renovation tasks that require reliable fixings where traditional mechanical anchors may underperform in porous materials.

Advantages

The chemical formulation bonds effectively with the pore structure of aerated concrete, reducing the risk of cracks and ensuring even load distribution around the threaded rod or bolt. The pack format ensures consistent material quality across multiple fixings and simplifies inventory for medium-sized installation jobs. Because it is engineered specifically for lightweight and cellular substrates, the anchor delivers improved pull-out values and greater design confidence compared with standard expansion anchors in the same substrate class.

Suitable for

• Anchoring threaded rods and bolts in aerated concrete and lightweight cellular blocks
• Structural and non-structural fixings such as rails, supports, and brackets
• Renovation and retrofit projects where substrate condition limits mechanical anchoring
• Installations requiring consistent, repeatable load-bearing connections

Key specifications

• Anchor type: chemical anchor designed for aerated concrete substrates
• Intended fasteners: threaded rods and bolts (compatible diameters per system instructions)
• Pack size: 25 anchors per pack
• Performance: high pull-out resistance and long-term bond stability in lightweight concrete
• Application temperature range and curing times: follow manufacturer technical data for specific conditions

How to use

Drill the hole to the recommended diameter and depth for the selected threaded rod or bolt, then thoroughly clean the hole of dust and debris before application. Inject the chemical resin into the hole from the back so the cavity fills from the bottom up, then insert the threaded rod or bolt slowly while rotating to ensure even resin distribution and eliminate air pockets. Allow the recommended curing time for the given temperature and substrate conditions before applying load. Follow all safety and handling instructions provided by the manufacturer and use appropriate personal protective equipment.

Usage recommendations

Use manufacturer technical tables to select correct drill diameter, embedment depth and curing time for the specific threaded rod diameter and substrate condition. Do not load anchors before full cure; in cold or damp environments expect extended curing times. For critical or structural applications consult project specifications or a structural engineer and verify compatibility with local building codes.
