Screw & anchor kit Fischer 534998 8 mm diameter 40 mm length

The Fischer 534998 screw & anchor kit contains eight 8 mm diameter, 40 mm long nylon anchors with matching screws. The DUOPOWER system combines two components — a grey high‑quality nylon part and a red expansion wing — which activate depending on the base material to provide optimal fixing through expansion, folding or knotting. The design includes a preshaped edge on the plug head to prevent the anchor from slipping into the drill hole, and the supplied screws are matched to the anchors for correct insertion and tightening.

Advantages

The two-component DUOPOWER design ensures very good holding values across different building materials by automatically activating the suitable fixing mechanism (expansion, folding or knotting). The red expansion wings support secure expansion and add safety to the grey component. The preshaped plug head edge prevents the anchor from slipping into the hole, and the kit includes screws matched to the anchors to allow easy and correct screwing without over‑tightening.

Suitable for

• Fixing light to medium loads in solid materials (concrete, solid brick)
• Fixing in cavities or hollow materials where folding or knotting is required
• General DIY and professional interior fastening tasks (shelves, brackets, fixtures)

How to use

Drill a hole with the recommended diameter and depth for an 8 mm anchor, remove drill dust, insert the DUOPOWER anchor until the preshaped edge rests on the surface, then insert the supplied screw and tighten evenly. The kit is designed so that the correct tightening closes the anchor and activates expansion, folding or knotting depending on the base material; avoid excessive force that could damage the anchor or the substrate.

Usage recommendations

Use appropriate drill bits and follow load tables for anchor spacing and edge distances. Choose solid or hollow fixing technique based on the wall material; when in doubt, test one anchor before installing multiple fixings.
