Fischer 43633 Threaded Anchor

The Fischer 43633 threaded anchor is a zinc‑plated steel internal threaded anchor designed for use with Fischer injection mortar in masonry, brick and autoclaved aerated concrete. It is set manually by lightly rotating the anchor into the mortar-filled drill hole so that the mortar bonds to the anchor surface and the drill-hole wall in solid brick; in hollow or perforated materials the mortar is pressed through the sleeve grid and forms an interlock with the base material. The anchor permits surface‑flush removal of the fixture and reuse of the fixing point when required.

Advantages

The internal threaded anchor FIS E is compatible with injection mortar for masonry and aerated concrete and features a metric internal thread that accepts standard metric screws or threaded rods. This design enables adaptable fastening solutions and allows surface‑flush removal and repeated reuse of the fixing point. The zinc‑plated steel construction provides corrosion protection appropriate for typical building applications. For load values and mortar-specific approvals, refer to the documentation of the injection mortar used.

Suitable for

• Anchoring in solid brick and masonry using injection mortar
• Fixings in autoclaved aerated concrete (AAC) with appropriate mortar
• Applications requiring surface‑flush removal and reuse of the fixing point

How to use

Drill the hole to the specified diameter and depth for the Fischer 43633 anchor. Clean the hole of dust and debris, inject the recommended Fischer injection mortar according to the mortar manufacturer’s instructions, then insert and set the internal threaded anchor by lightly rotating it so the mortar fully surrounds the anchor sleeve. Allow the mortar to cure for the time specified by the mortar manufacturer before applying load. Use standard metric screws or threaded rods in the internal thread for the final fixture.

Recommendations

Use only approved injection mortars and follow the mortar approval and processing instructions for the specific base material. Verify required drill diameter, embedment depth and curing time from the mortar documentation and the relevant approvals to achieve the specified load values.
