Ekspanzijski tipl Fischer 568108

The Expansion anchor Fischer 568108 is a nylon expansion plug designed for reliable fastening in a variety of building materials including autoclaved aerated concrete, brick, concrete, gypsum fibre board and general masonry. With an outer diameter of 8 mm and a length of 65 mm, this anchor is supplied in boxes of 50 pieces and is intended for use with an 8 mm drill hole. The nylon construction provides durable performance and maintains holding strength across solid and perforated substrates.

Advantages

The anchor uses a four-way expansion mechanism to transmit forces evenly into the base material, delivering high holding values in both solid and perforated materials. Integrated fixing blades provide pre-fixation of the screw so the fastener remains in place during setting, which simplifies overhead and one-person installations. A neck design that avoids expansion forces at the surface reduces risk of damage to tiles and plaster during screw insertion. The plug’s geometry allows easy placement into the drill hole with minimal hammering, and the larger anchorage depth improves performance in hollow building materials and aerated concrete. A pronounced tightening torque gives tactile feedback when the screw is correctly set, helping to avoid overtightening.

Suitable for

• Fastening fixtures to autoclaved aerated concrete (cellular concrete)
• Anchoring into brick and masonry
• Fixings in solid concrete and sand-lime brick
• Mounting on gypsum fibre board where compatible
• Use in hollow building materials and for bridging plaster

Key specifications

• Material: nylon
• Anchor diameter: 8 mm
• Anchor length: 65 mm
• Recommended drill hole diameter: 8 mm
• Pack quantity: 50 pieces

How to use

Drill a hole with an 8 mm bit to the required depth and clean the hole of dust and debris. Insert the nylon anchor fully into the drill hole; the plug shape allows positioning with a few light hammer blows if needed. Use a compatible screw (length = anchor length + fixture thickness + screw diameter) and begin tightening. During screw insertion the integrated blades pre-fix the screw and the anchor expands in four directions to engage the substrate. Tighten until tactile resistance indicates the anchor is set; avoid excessive torque once proper set is felt.

Recommendations

For stable results choose screws compatible with anchors for masonry or wood/chipboard as appropriate. Use the anchor in materials listed above and verify that drill depth and screw length match the fixture thickness. For overhead installations, the pre-fixation blades assist single-person fitting. Do not use the anchor in materials or applications not suited to nylon expansion plugs or beyond the mechanical limits of the substrate.
