Screw anchor (wall plug) FISCHER 045487 — pack of 10, for screw mounting

The Fischer expansion plug S is a proven universal wall plug made of high-quality nylon, designed for secure fixing in concrete and solid masonry. Each pack contains 10 plugs suitable for use with wood or chipboard screws. The plug expands in two directions and can be rotated to direct expansion forces parallel to the edge of the base material, reducing the risk of spalling when fixing close to edges.

Advantages

The nylon construction provides robustness during installation and long-term retention. The plug’s two-way expansion and the possibility to turn it before tightening help control load direction and protect fragile edges of the building material. It accepts standard wood or chipboard screws, offering versatile use for a range of fixtures.

Suitable for

• Anchoring fixtures in concrete
• Fixing in solid masonry (brick, stone)
• Mounting shelves, brackets and light fittings using wood or chipboard screws

When it may not be suitable

This plug is not intended for use in hollow or perforated masonry where a cavity prevents proper two-directional expansion. It is also not suitable where metal anchors or chemical anchors are required for very high loads or vibration-prone applications.

Key specifications

• Material: high-quality nylon
• Expansion type: two-directional expansion (controllable by rotating the plug)
• Length: 50 mm (per offer information)
• Pack quantity: 10 pieces
• Suitable screw type: wood or chipboard screws

How to use

Drill a hole of the correct diameter and depth for the 50 mm plug, clean the hole from dust, and insert the plug either flush or as a push-through insertion. Turn the plug if necessary to align the expansion direction parallel to the edge of the base material. Insert an appropriate wood or chipboard screw and tighten until the plug expands and holds securely in the masonry or concrete.

What to consider before purchase

• Confirm base material is solid (concrete, solid brick or stone)
• Match drill hole diameter and depth to the plug size (50 mm length)
• Choose compatible wood or chipboard screws for the intended load

Usage recommendations

For edge fixings, rotate the plug so the expansion runs parallel to the edge to minimise risk of spalling; use appropriate screw length to ensure sufficient engagement without over-tightening.
