Screw anchor FISCHER 536188 long-shaft wall plug, pack of 4

The fischer frame fixing SXRL FUS is a long-shaft frame anchor designed for multiple fixings of non-load-bearing systems in masonry, concrete and aerated concrete. It is supplied together with a hexagon-head safety screw with moulded washer and integrated TX40 bit holder, and the zinc‑plated steel screw is suitable for the installation of façade, ceiling and roof substructures made of metal. The anchor features two expansion zones that distribute forces evenly in perforated masonry and combine into a long expansion element in aerated concrete and solid materials.

Advantages

The SXRL FUS provides reliable load values for multiple fixings in concrete and masonry due to its assessed expansion behaviour. Its long expansion element and geometry ensure even load distribution to the base material, reducing the risk of damaging thin fillets in lightweight masonry. Ribs on the plug prevent rotation during installation and simplify assembly.

Suitable for

• Fixing metal substructures for façades and curtain-wall supports
• Mounting ceiling and roof substructures made of metal
• Securing non-structural systems in solid concrete and masonry
• Installations in aerated concrete where a long expansion element is needed

When it may not be suitable

This anchor is intended for non-load-bearing systems and is not designed for primary structural connections where load-bearing anchors are required. It may not be appropriate for very thin or fragile finishes where the visible washer or screw head could cause damage or where a flush or concealed fixing is required.

Key specifications

• Anchor type: long-shaft frame fixing with two expansion zones
• Material (screw): zinc-plated steel
• Drive/bit type: TX40 integrated bit holder
• Suitable base materials: masonry, perforated masonry, concrete, aerated concrete
• Application: multiple fixings of non-load-bearing metal substructures

How to use

Drill a hole of the specified diameter and depth for the long-shaft anchor, clean the hole of dust, insert the anchor fully and position the metal substructure. Drive the hexagon-head safety screw with a TX40 driver until the washer bears against the fixture and the anchor expands to engage the base material. Ensure the screw is tightened to the recommended torque for the specific substrate and avoid over-torquing.

What to consider before purchase

• Confirm compatibility with the thickness and type of base material (concrete, masonry, aerated concrete)
• Check required anchor length versus installation depth and fixture thickness
• Determine whether a visible washer-head anchor suits the aesthetic and functional requirements

Usage recommendations

Use the SXRL FUS for non-structural metal substructures where even load distribution is important. Follow drilling and torque specifications for the substrate, and use the integrated TX40 bit for reliable screw engagement.
