Bucha de expansão Fischer 562157 120 mm Nylon 50 unid.

Fischer 562157 is a 120 mm nylon expansion anchor designed for reliable fixing in concrete, gypsum block, and masonry. Supplied in a box of 50 pieces, this anchor combines a grey high-quality nylon body with a red flexible component and includes a pre-mounted safety screw. The DuoXpand geometry allows installation by push-through method and delivers even load distribution in solid substrates while gently expanding in perforated masonry to form an undercut without damaging porous webs. The product is suitable for non-structural applications and is particularly useful for fastening wood to concrete or masonry.

Advantages

The combination of design and material adapts to all building materials and enables universal use. The grey main body made of high-quality nylon provides strength, while the red material component ensures flexibility and optimal spreading. A pre-mounted safety screw is matched to the plug for time savings during installation. The special lamella geometry expands gently in the respective building material, avoiding fractures in porous materials and enabling anchoring close to edges. An ETA for multiple use in non-structural applications ensures secure hold across building-material classes.

Suitable for

• Fixing wood to concrete or masonry
• Anchoring fixtures in concrete and solid masonry
• Use in perforated brickwork where undercut anchoring is required
• General non-structural interior and exterior attachments

How to use

Drill a hole with a 10 mm drill bit to at least 130 mm depth. Clean the hole of dust and insert the Fischer 562157 anchor by push-through installation. Place the fixture against the substrate, then drive the pre-mounted safety screw into the anchor until the lamellas expand and the anchor seats firmly. Ensure the screw length is appropriate for the thickness of the fixture and substrate application.

Recommendations

Use the anchor in accordance with the European Technical Assessment for multiple use in non-structural applications. In perforated masonry, ensure correct hole depth so the lamellas can form an undercut at the stone web. Avoid overtightening to prevent damage to porous substrates and select screw length suitable for secure engagement.
