Expansion anchor Fischer 567857 8 mm diameter 65 mm length 10 pcs

Fischer 567857 is an 8 mm diameter, 65 mm long nylon expansion anchor designed for secure fixings in solid and perforated building materials including autoclaved aerated concrete, brick and masonry. Supplied in packs of 10, this expansion anchor features a longer anchorage depth that makes it particularly suitable for hollow building materials and applications requiring bridging of plaster.

Advantages

The 4-way expansion provides efficient force transmission into the base material and ensures high load values in both solid and perforated substrates. Built-in fixing blades pre-fix the screw so the installer does not need to hold the screw during setting, which is useful for overhead work. An expansion-free plug neck prevents surface expansion forces while tightening, reducing the risk of damage to tiles and plaster. The plug’s shape allows easy placement into the drill hole with a few light hammer blows, and the flexible plug edge prevents the plug from slipping deeper into the hole. Made from high-quality nylon, the anchor guarantees a permanent, reliable hold.

Suitable for

• Autoclaved aerated concrete (AAC)
• Brick and masonry
• Hollow building materials and plastered substrates
• Applications requiring overhead or pre-positioned installation

How to use

Drill a hole of the correct diameter and depth for the 8 mm anchor. Clean the hole from dust, insert the anchor either flush with the substrate (pre-positioned) or push it through the fixture, and place it fully into the drilled hole. Insert the appropriate wood, chipboard or stud screw; the fixing wings fold inwards to hold the screw during installation. Tighten the screw until the anchor expands in four directions and locks into the base material. The required screw length equals plug length + fixture thickness + screw diameter.

Usage recommendations

Use the SX Plus anchor with screws suitable for the chosen substrate (wood, chipboard or stud screws). Ensure correct drill diameter and embedment depth. For plastered or hollow materials, the increased anchorage depth of this variant improves performance. Avoid overtightening once noticeable tightening torque indicates correct installation.
