Screw & wall plug kit Fischer 522699

The fischer frame fixing SXRL-T is a kit component designed for multiple fixings of non-load-bearing systems in masonry, concrete and autoclaved aerated concrete. Supplied with a countersunk head safety screw with TX40 drive made of zinc-plated steel, the fixing transfers forces into the substrate via two expansion zones that work together as a long expansion element in aerated concrete and solid building material. The SXRL-T is suitable for internal frame installations such as windows, coat racks, wall cupboards and TV consoles and is available in a 50‑piece kit (Fischer 522699) with plugs 10 mm in diameter and 100 mm length.

Advantages

The long expansion element with multiple anchorage depths (50, 70 and 90 mm) allows flexible installation depths and makes the SXRL-T suitable for a wide range of fixing situations. The special plug geometry distributes retention forces evenly inside the drill hole, reducing point loads on the base material. The product is approved for single-point fixing in cracked concrete, which makes it a suitable choice for certain outdoor and structural frame applications compared with standard steel anchors. Longer peripheral ribs on the plug prevent twisting during deep setting and ease installation.

Suitable for

• Internal window frame fixings
• Mounting coat racks and wall cupboards
• Installing TV consoles and shelving
• Fixings in aerated concrete, brick and solid masonry

How to use

Drill a 10 mm hole to the required depth corresponding to the chosen anchorage length, clean the hole of dust, insert the SXRL-T plug flush with the surface and drive the supplied countersunk TX40 safety screw until the plug expands and anchors in the base material. Choose the appropriate anchorage depth (50, 70 or 90 mm) based on the substrate and load requirements. Follow drilling and torque specifications provided by the manufacturer for each material type.

Usage recommendations

Use the fitted TX40 countersunk safety screw delivered with the kit and select the anchorage depth according to the building material. For installations in cracked concrete or critical applications, verify approval and follow local standards. Avoid using the SXRL-T for load-bearing structural elements beyond the approved single-point fixing limits.
