Expansion anchor Fischer 41648

The Fischer 41648 expansion anchor is a nylon screw anchor engineered for secure fixing in brick, concrete and masonry. Supplied in a box of 132 pieces, this anchor is intended for general-purpose fastening where reliable load distribution and simple installation are required. The nylon construction resists corrosion and provides dimensional stability for interior and exterior applications when used in appropriate base materials.

Advantages

Made from durable nylon, the Fischer expansion anchor offers consistent performance across common building substrates. Its expansion design ensures positive contact with hole walls to deliver dependable holding strength. Supplied in a large quantity per box, it reduces the need for frequent reordering on medium and larger projects. The anchors are compatible with standard wood or metal screws and install with common drilling tools and screwdrivers.

Suitable for

• Mounting shelving and cabinets to brick or concrete walls
• Fixing lightweight to medium-weight fixtures in masonry
• Electrical boxes and conduit supports in solid substrates
• General DIY and renovation fastening tasks

How to use

Select a drill bit matching the anchor outer diameter and drill a hole to the required depth in the base material. Clean the drilled hole from dust and debris, then insert the nylon expansion anchor fully into the hole. Place the fixture against the substrate, insert the appropriate screw through the fixture into the anchor, and tighten until the anchor expands and secures against the hole walls. Do not over-tighten screws to avoid deforming the anchor. Follow manufacturer guidance for drill diameter and embedment depth for the chosen screw size.

Usage recommendations

Use the Fischer nylon expansion anchors only in suitable solid substrates such as concrete, brick or dense masonry. For hollow or insulated walls, select an anchoring system designed for those conditions. Verify screw diameter and length to ensure correct engagement and safe load performance. Where load values are critical, consult structural guidelines or perform load testing before final installation.
