Screw anchor FISCHER 536187 long-shaft wall plug set, 4 pieces, model SXRL 10 x 140

The Fischer SXRL FUS frame fixing is a long-shank frame anchor designed for multiple fixings of non-load-bearing systems in masonry, concrete and aerated concrete. The anchor combines a two-zone expansion sleeve with a zinc‑plated safety screw featuring an integrated bit holder and moulded washer. Its geometry distributes loads evenly and the long expansion element makes it suitable for thin-walled and solid base materials. Supplied in sets of four, this product is intended for façade, ceiling and roof substructure connections in metal subframes.

Advantages

The SXRL FUS provides reliable load transfer through two expansion zones that either act individually in perforated masonry or form a continuous expansion element in aerated concrete and solid materials. The fixing geometry reduces stress on thin fillets and prevents damage during installation. Ribs on the sleeve stop rotation of the plug for easier assembly, while the zinc‑plated safety screw with moulded washer and integrated bit holder ensures consistent, secure fastening.

Suitable for

• Fixing non-load-bearing façade subframes made of metal
• Attaching ceiling and roof substructures to concrete or masonry
• Installation in aerated concrete where a long expansion element is required
• Use in solid concrete and perforated masonry

When it may not be suitable

The SXRL FUS is not intended for structural load-bearing connections where certified structural anchors are required. It may not be appropriate for very thin or brittle finishes where surface damage must be avoided unless the substrate beneath provides sufficient strength. For special base materials or seismic applications, check applicable standards and use anchors specified for those conditions.

Key specifications

• Anchor type: long-shank frame fixing with two expansion zones
• Material: zinc‑plated steel screw; plastic expansion sleeve
• Recommended use: non-load-bearing metal subframes for façades, ceilings, roofs
• Base materials: concrete, masonry, aerated concrete
• Pack quantity: 4 pieces per set

How to use

Drill a hole to the specified diameter and embedment depth for the anchor, clean the hole of dust, insert the sleeve fully, then drive the zinc‑plated safety screw with the appropriate TX40 bit until the sleeve expands and the fixing is secure. Ensure the screw head and moulded washer are seated against the fixture and verify correct engagement of the bit holder. Follow manufacturer drilling and embedment recommendations for different base materials.

What to consider before purchase

• Verify substrate type (concrete, perforated masonry, aerated concrete) and required embedment depth
• Confirm that the application is non-load-bearing and within the anchor's intended use
• Ensure the correct drill diameter and TX40 drive are available

Usage recommendations

Use the Fischer SXRL FUS for repeated, reliable fixings of metal frame substructures in common building materials; always follow the recommended hole cleaning, drill size and embedment depth for the chosen substrate and use the TX40 bit for proper screw engagement.
