Koelner/Rawlplug quick-fit dowels 6 x 40 mm with flange, pack of 35, are designed for anchoring screws in masonry, concrete and other solid base materials. The flanged head prevents the plug from slipping into the drilled hole and helps distribute load at the surface, making these dowels suitable for light to medium fixing tasks. Each dowel expands reliably when a matching screw is driven in, creating a secure hold for fixtures where compact, easy installation is required.
Advantages
The quick-fit design allows fast installation with minimal preparation: drill the specified hole, insert the dowel until the flange rests against the surface and drive in the screw. The flange reduces countersinking and improves load distribution across the surface. Made to work in solid substrates, these dowels deliver consistent expansion and stable anchoring for common household and professional mounting jobs. Supplied in a pack of 35, they are convenient for small renovation or repair projects.
Suitable for
- Mounting shelves and light cabinets to masonry or concrete walls
- Securing curtain rails, hooks and brackets
- Fixing electrical boxes, conduit clips and small fixtures
- General-purpose DIY repairs and apartment fitting tasks
Key specifications
- Diameter: 6 mm
- Length: 40 mm
- Head type: flanged (prevents over-insertion)
- Material: corrosion-resistant plastic (suitable for masonry and concrete)
- Pack quantity: 35 pieces
- Intended load class: light to medium loads in solid substrates
How to use
Select a screw diameter that matches the dowel specification, typically recommended for 6 mm dowels. Drill a hole of the correct diameter and depth into the masonry or concrete, clean out dust, and insert the dowel until the flange sits flush to the surface. Place the fixture over the dowel, align the screw, and drive it in until the dowel expands and secures the fitting. Avoid over-tightening the screw to prevent deforming the dowel or damaging the substrate.
Usage recommendations
Use these dowels only in solid materials such as brick, concrete or solid stone. Do not use in hollow blocks or lightweight aerated concrete without verifying suitability or using an appropriate anchor type. For heavier loads or critical fixings, consult load tables or use appropriate heavy-duty anchors. Store in a dry place away from direct sunlight to preserve material properties.
