Screw anchor wall plug FISCHER 045461 – pack of 20, universal anchor for screws

The fischer universal fixing FU is an all-purpose wall plug made of high-quality nylon designed for a wide range of building materials. It expands reliably in solid substrates such as concrete and aerated concrete and locks or buckles in perforated and panel materials to provide a secure hold. The fixing accepts wood and chipboard screws and is suitable for through-type installation of lamps, cornices, lightweight shelves and wall cabinets.

Advantages

The universal nylon anchor offers firm holding strength across many substrates while its expansion mechanism and sleeve buckling adapt to both solid and hollow materials. An integrated collar prevents the plug from falling into drill holes, and an anti-rotation feature reduces turning during screw insertion. Compatible with common wood and chipboard screws, it supports straightforward through-fixing installations.

Suitable for

• Mounting lamps and light fixtures
• Fixing cornices and moldings
• Installing lightweight shelves and wall cabinets
• General fixtures into concrete, aerated concrete, masonry, plasterboard and hollow blocks

When it may not be suitable

This nylon universal fixing is intended for light to medium-duty applications; it may not be appropriate for very heavy loads or critical structural fixings where metal anchors or chemical anchors are specified. For applications requiring high shear or tensile loads, consult load tables and choose an anchor specifically rated for those forces.

Key specifications

• Material: high-quality nylon
• Suitable screw type: wood and chipboard screws
• Installation type: through-type fixing
• Works in: solid materials (concrete, aerated concrete) and hollow/perforated materials (plasterboard, hollow blocks, panels)
• Pack quantity: 20 pieces

How to use

Drill a hole of the correct diameter and depth for the chosen plug, remove dust from the hole, insert the nylon fixing until the collar sits flush with the surface, and then drive a suitable wood or chipboard screw. In solid substrates the plug expands; in hollow or panel substrates the sleeve buckles to form a secure anchorage. Ensure screw length and diameter match the fixing and the item being mounted.

What to consider before purchase

• Confirm the substrate type (solid or hollow) to ensure the universal fixing is appropriate
• Choose correct drill bit diameter and screw size compatible with the plug
• Assess the weight of the load and mounting method to verify suitability for light to medium loads
• Check pack quantity to match the number of fixings required

Usage recommendations

For reliable results, use clean, correctly sized drill holes and compatible wood or chipboard screws. Avoid using this plastic anchor for heavy structural loads; where higher capacities are needed, select metal or chemical anchors designed for those applications.
