Bucha de expansão Fischer 562171 160 mm para betão bloco de gesso alvenaria

Fischer 562171 is a 160 mm expansion anchor designed for secure fastening in concrete, gypsum block and masonry. Made of high-quality nylon with a two-color design, the anchor combines strength and flexibility for reliable performance in a wide range of non-structural applications. The pack contains 50 pieces and is intended for push-through installation with a drill hole diameter of 10 mm and a minimum embedment depth of 170 mm.

Advantages

The grey main body of the expansion anchor is manufactured from durable nylon to provide load resistance, while the red component supplies flexibility and ensures optimal expansion. A pre-mounted safety screw matched to the plug reduces installation time. The lamella geometry expands gently in different substrates, minimising the risk of fractures in porous materials and enabling anchoring close to edges. The product has a European Technical Assessment (ETA) for multiple use in non-structural applications, ensuring reliable hold across building material classes.

Suitable for

• Concrete
• Gypsum block
• Masonry and perforated brickwork

How to use

Drill a hole with a 10 mm diameter to the required depth of at least 170 mm, remove drill dust, insert the Fischer 562171 anchor by push-through installation, and tighten the pre-mounted safety screw until the anchor expands and securely engages the substrate. In perforated materials, the lamellas expand at the stone web to form an undercut; in solid substrates the design distributes loads evenly into the base material.

Recommendations

Use the specified drill diameter and embedment depth for correct performance. Clean the hole of dust before insertion. For edge distances and spacing follow applicable ETA guidance and local building codes. Avoid using the anchor for structural load-bearing applications beyond its ETA scope.
