Screw anchor FISCHER 532666 — pack of 4, wall plug set for fastening

The Fischer expansion plug S is a proven nylon wall plug designed for secure anchoring in concrete and solid masonry. Made entirely from high-quality nylon, it offers robust performance during installation and durable hold over time. The plug expands in two directions and can be rotated so expansion forces run parallel to the edge of the base material, reducing the risk of spalling when fixing near edges. Suitable for use with wood or chipboard screws, the Fischer S plug is supplied here as a set of four.

Advantages

The all-nylon construction provides good resilience and resistance to breakage during insertion while ensuring a long-lasting connection in solid substrates. Controlled two-direction expansion allows targeted transmission of forces, and the rimless design supports both pre-positioned and push-through installation. An anti-rotation lock prevents the plug from turning in the drill hole, increasing installation reliability.

Suitable for

• Anchoring in concrete
• Anchoring in solid masonry (brick, solid blocks)
• Fixing with wood screws or chipboard screws
• Installations near material edges where reduced spalling risk is required

When it may not be suitable

This expansion plug is not intended for use in hollow or perforated masonry where an anchor with through-bolt or chemical fixing may be more appropriate. It is also not specified for load-bearing steel-to-concrete structural connections that require specialized anchors tested for those applications.

Key specifications

• Material: high-quality nylon (plastic)
• Expansion type: two-directional expansion
• Design: rimless plug with anti-rotation lock
• Suitable screw types: wood screws, chipboard screws
• Intended substrates: concrete and solid masonry
• Pack quantity: 4 pieces

How to use

Drill a hole in the substrate to the recommended diameter and depth for this plug, clean the hole of dust, then insert the plug either pre-positioned or by push-through installation. Turn the plug if needed to align the expansion direction parallel to the material edge. Insert the appropriate wood or chipboard screw and tighten to secure the fixture without over-torquing.

What to consider before purchase

• Confirm substrate type is solid (concrete or solid masonry).
• Match drill bit diameter and screw type to the plug size.
• Consider distance from edges and required embedment depth for the application.

Usage recommendations

For best results, use the plug with recommended screw diameters and ensure the drill hole is cleared of debris before insertion. When anchoring close to edges, rotate the plug so expansion forces run parallel to the edge to reduce the risk of spalling.
