Expansion anchor Fischer 567820 20 mm Nylon 50 pcs

Fischer 567820 is a nylon expansion anchor designed for secure fixing in solid building materials. With a 20 mm length and 4 mm drill-hole diameter, this pack of 50 anchors is suitable for use in concrete, masonry, sand-lime brick and similar substrates where reliable mechanical anchoring is required.

Advantages

The 4-way expansion transfers forces evenly into the base material and ensures high load values in both solid and perforated building materials. Special fixing wings pre-fix the screw so the user has both hands free during installation. An expansion-free plug neck prevents expansion forces at the material surface while screwing, reducing the risk of damage to tiles or plaster. The plug’s shaped body permits easy insertion into the drill hole with a few light hammer blows, and a pronounced plug edge prevents the anchor from slipping deeper into the hole. A noticeable tightening torque signals proper installation and helps to avoid overtightening.

Suitable for

• Concrete and solid masonry
• Sand-lime brick
• Autoclaved aerated concrete and gypsum block
• Fixing with wood, chipboard or stud screws

How to use

Drill a hole with a 4 mm bit to the required depth, clean the hole of dust, then insert the Fischer 567820 anchor until the pronounced edge rests on the substrate surface. For pre-positioned or push-through installation, position the fixture and insert the screw. The fixing wings fold inward when the anchor is inserted and hold the screw in place; tighten the screw until the anchor expands in four directions and securely anchors in the base material.

Usage recommendations

Use appropriate screw lengths: screw length = anchor length + fixture thickness + screw diameter. Choose wood, chipboard or stud screws compatible with a 4 mm anchor and avoid overtightening once a clear tightening torque is felt. Clean drill holes before installation and use the anchor in suitable solid or perforated substrates as specified.
