These wall plugs are designed for use with 5mm, 6mm, and 7mm drill bits. The specific dimensions of the plug itself vary slightly based on the intended drill size.

Yes, Fischer Plastic Contract Wall Plugs are suitable for use in solid building materials like brick, as well as hollow materials like plasterboard.

The weight-bearing capacity depends on the specific building material and the size of the plug and screw used. Always consult the product packaging or Fischer's technical data for specific load limits. They are generally suitable for light to medium-duty applications.

The locks are small protrusions or fins on the side of the plug that grip the inside of the drilled hole, preventing the plug from spinning freely when a screw is inserted or removed.

The colors typically correspond to the different sizes or types of plugs. In this case, the pack contains a mix of Red, Brown, and Grey plugs, likely representing the 5mm, 6mm, and 7mm variants for easy identification.

You need a standard masonry drill bit or a wood drill bit of the correct diameter (5mm, 6mm, or 7mm) depending on the plug size you are using.

Ensure you have used the correct drill bit size for the plug. The hole may be slightly too large. Try a slightly larger plug if available, or ensure the anti-rotation locks are properly seated.

Verify that the correct drill bit size was used. The hole may be too small. Re-drill the hole with the specified bit size, ensuring it is clean and to the correct depth.

Check that the plug is fully seated in the wall. The building material might be too soft or degraded. Ensure the screw is compatible with the plug size and material type.
